                          LINEAR TECHNOLOGY CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

1.   Interim financial statements and information are unaudited; however, in the
     opinion of  management  all  adjustments  necessary for a fair and accurate
     presentation  of the interim  results have been made. All such  adjustments
     were of a normal  recurring  nature.  The  results  for the  three and nine
     months ended March 30, 2003 are not necessarily an indication of results to
     be expected for the entire fiscal year.  All  information  reported in this
     Form  10-Q  should  be  read  in  conjunction  with  the  Company's  annual
     consolidated  financial  statements for the fiscal year ended June 30, 2002
     included in the Company's Annual Report to  Stockholders.  The accompanying
     balance  sheet at June 30, 2002 has been  derived  from  audited  financial
     statements  as of that  date.  Because  the  Company  is viewed as a single
     operating segment for management purposes,  no segment information has been
     disclosed.

2.   The Company operates on a 52/53 week year ending on the Sunday nearest June
     30. Fiscal years 2003 and 2002 are 52-week years.

3.   Basic earnings per share is calculated using the weighted average shares of
     common stock outstanding  during the period.  Diluted earnings per share is
     calculated using the weighted  average shares of common stock  outstanding,
     plus the dilutive  effect of stock  options  calculated  using the treasury
     stock method. The following table sets forth the reconciliation of weighted
     average  common shares  outstanding  used in the  computation  of basic and
     diluted earnings per share:

4.   Stock-Based Compensation

     The Company  has  adopted  the  disclosure  requirements  of  Statement  of
     Financial   Accounting  Standards  No.  148  (SFAS  148,)  "Accounting  for
     Stock-Based  Compensation - Transition and Disclosure"  effective March 30,
     2003. SFAS 148 amends Statement of Financial  Accounting  Standards No. 123
     (SFAS  123),   "Accounting  for  Stock-Based   Compensation,"   to  provide
     alternative  methods of transition for a voluntary change to the fair value
     based method of accounting for stock-based compensation and also amends the
     disclosure  requirements  of SFAS 123 to require  prominent  disclosures in
     both  annual  and  interim  financial   statements  about  the  methods  of
     accounting  for  stock-based  employee  compensation  and the effect of the
     method used on reported results. As permitted by SFAS 148 and SFAS 123, the
     Company continues to apply the accounting provisions of APB 25, and related
     interpretations,  with regard to the measurement of  compensation  cost for
     options granted under the Company's equity  compensation plans. No employee
     compensation  expense  has been  recorded  as all  options  granted  had an
     exercise price equal to the market value of the underlying  common stock on
     the date of grant.  Had expense been recognized using the fair value method
     described in SFAS 123, using the  Black-Scholes  option-pricing  model, the

5.   Accumulated Other Comprehensive Income

     Accumulated  other  comprehensive  income  consists of unrealized  gains on
     available-for-sale  securities.  The Company, in practice,  primarily holds
     its cash and  short-term  investments  until  maturity.  The  components of
     comprehensive income were as follows:

6.   Recent Accounting Pronouncements

     In June 2001,  the  Financial  Accounting  Standards  Board  (FASB)  issued
     Statement of Financial  Accounting  Standards  No. 142  "Goodwill and Other
     Intangible  Assets"  (SFAS  142).  SFAS  142  requires  that  goodwill  and
     indefinite lived intangible assets are no longer amortized but are reviewed
     annually  (or  more   frequently  if  impairment   indicators   arise)  for
     impairment.  Separable  intangible  assets  that are not  deemed to have an
     indefinite life will continue to be amortized over their useful lives.  The
     Company  adopted SFAS 142 on July 1, 2002. The adoption of SFAS 142 did not
     have  any  impact  on  the  Company's  financial  position  or  results  of
     operations.

     In October 2001,  the Financial  Accounting  Standards  Board (FASB) issued
     Statement of Financial  Accounting  Standards No. 143 "Accounting for Asset
     Retirement  Obligations"  (SFAS 143). SFAS 143 requires that the fair value
     of asset retirement  obligations be recognized as a liability when they are
     incurred  and that the  associated  retirement  costs be  capitalized  as a
     long-term asset and expensed over its useful life. The Company adopted SFAS
     143 on July 1, 2002.  The  adoption  of SFAS 143 did not have any impact on
     the Company's financial position or results of operations.

     In August 2001,  the  Financial  Accounting  Standards  Board (FASB) issued
     Statement of Financial  Accounting  Standards No. 144,  "Accounting for the
     Impairment or Disposal of Long-Lived Assets" (SFAS 144). SFAS 144 addresses
     financial  accounting  and  reporting  for the  impairment  or  disposal of
     long-lived  assets  and  supersedes  FAS  No.  121,   "Accounting  for  the
     Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed
     Of," and the accounting and reporting  provisions of APB No. 30, "Reporting
     the Results of Operations  for a Disposal of a Segment of a Business."  The
     Company  adopted SFAS 144 on July 1, 2002. The adoption of SFAS 144 did not
     have  any  impact  on  the  Company's  financial  position  or  results  of
     operations.

     In June 2002,  the  Financial  Accounting  Standards  Board  (FASB)  issued
     Statement of Financial  Accounting Standards No. 146, "Accounting for Costs
     Associated with Exit or Disposal Activities" (SFAS 146.) SFAS 146 addresses
     financial  accounting  and  reporting  for  costs  associated  with exit or
     disposal   activities  and  nullifies  EITF  Issue  No.  94-3,   "Liability
     Recognition for Certain  Employee  Termination  Benefits and Other Costs to
     Exit an Activity (including Certain Costs Incurred in a Restructuring)" and
     must be  applied  beginning  January  1,  2003.  SFAS 146  requires  that a
     liability  for a cost  associated  with  an exit or  disposal  activity  be
     recognized  when the  liability  is  incurred  rather than when the exit or
     disposal  plan  is  approved.  The  adoption  of  SFAS  146  has  not had a
     significant  effect on the  Company's  financial  position  or  results  of
     operations.

     In November 2002, the Financial  Accounting  Standards  Board (FASB) issued
     Interpretation No. 45, "Guarantor's  Accounting and Disclosure Requirements
     for Guarantees,  Including  Indirect  Guarantees of Indebtedness of Others"
     (FIN 45.) FIN 45 elaborates  on the existing  disclosure  requirements  for
     most  guarantees,  including  loan  guarantees  such as standby  letters of
     credit, and provides new disclosure requirements regarding  indemnification
     provisions.  FIN 45 also  clarifies that at the time a guarantee is issued,
     the Company must  recognize an initial  liability for the fair value of the
     obligations   it  assumes  under  the  guarantee  and  must  disclose  that
     information  in  its  financial  statements.   The  provisions  related  to
     recognizing  a liability  at  inception  of the  guarantee  do not apply to
     product warranties, indemnification provisions, and to guarantees accounted
     for as derivatives.  The initial  recognition  and  measurement  provisions
     apply on a  prospective  basis  to  guarantees  issued  or  modified  after
     December 31, 2002,  and the  disclosure  requirements  apply to  guarantees
     outstanding  as of December 31, 2002. The adoption of FIN 45 did not have a
     significant  effect on the  Company's  financial  position  or  results  of
     operations.  FIN 45 also requires additional  disclosures by a guarantor in
     its  interim  and  annual   financial   statements  about  the  obligations
     associated with guarantees  issued. As disclosed in the Company's Form 10-K
     for the year ended June 30, 2002, the Company's  warranty  policy  provides
     for  replacement  of  defective  parts,   however,   warranty  expense  has
     historically been negligible.

         Net sales for the quarter ended March 30, 2003 were $153.8 million,  an
increase  of $23.6  million or 18.1% over net sales for the same  quarter of the
previous year. The increase in net sales was due to higher unit shipments, which
was offset by a decrease in the average  selling price.  The decrease in average
selling  price is the result of a  continuing  change in mix to smaller  package
products and due to slight price reductions when compared to the previous fiscal
year. Sales increased in Japan,  rest of the world (ROW) which is primarily Asia
excluding Japan, and the United States.  Sales in Europe were down slightly when
compared  to  the  third  quarter  of  fiscal  2002.  International  sales  were
approximately  68% of net sales for the third quarter of fiscal 2003 compared to
64% for the third quarter of fiscal 2002. International geographies as a percent
of worldwide net sales were ROW 35%,  Europe 17%, and Japan 16%.  Domestic sales
were  approximately  32% of net  sales  for the third  quarter  of  fiscal  2003
compared  to 36% for the third  quarter  of fiscal  2002.  The  Company's  major
end-market  applications  are  communications,  industrial  and computer.  Sales
increased  over the prior  year's  quarter  in each  end-market  application  in
absolute dollars, led by communications.

         Net sales for the nine  months  ended March 30,  2003  increased  $69.3
million or 18.6% over net sales for the same period of the previous fiscal year.
The increase in net sales was due to higher unit shipments,  which was partially
offset by a decrease  in the  average  selling  price.  Sales  increased  in all
geographic areas, led by ROW,  followed by Japan,  Europe and the United States.
Relative to end-market applications,  sales increased over the prior year's nine
month  period  in  each  of  the  Company's  three  major  end-markets,  led  by
communications.

         During the third  quarter of fiscal 2003,  the Company had one one-week
shutdown  during the New Years holiday week.  This resulted in one fewer week of
shutdown when compared to the third quarter of the previous fiscal year. For the
first nine months of fiscal 2003 the Company had four fewer  one-week  shutdowns
compared to the same period in the  previous  fiscal  year.  Due to having fewer
shutdowns  during the third quarter and for the first  nine-months,  the Company
had  greater  compensation  costs  throughout  the cost of sales  and  operating
expense lines.

                                       10


         Gross  profit  increased  $18.7  million or 19.6% and $62.6  million or
23.7% for the third quarter and first nine months of fiscal 2003,  respectively,
over the corresponding periods in fiscal 2002. The increase in gross profit as a
percentage  of net sales for both  periods was  primarily  due to the  favorable
effect  of  fixed  costs  allocated  across  a  higher  sales  base as well as a
reduction in headcount  expenses from the previous  fiscal year. The decrease in
average  selling price referred to above did not have a  commensurate  effect on
gross margin since most of the  reduction  was due to a change in product mix as
the Company has had  increased  sales of products  with  smaller die and package
types, which have a smaller average selling price but also lower costs.

         Research and development  ("R&D") expenses increased by $2.5 million or
12.3% and $8.7  million or 14.9% for the third  quarter and first nine months of
fiscal 2003,  respectively,  as compared to the same periods in fiscal 2002. The
increase in R&D  expenses  compared to the prior year  periods was mainly due to
increases in labor expenses  primarily  related to increases in profit  sharing,
engineering  headcount,  and the impact of fewer shutdowns during the periods as
explained  above. The increases in labor costs were offset by a decrease in mask
costs.

         Selling, general and administrative expenses ("SG&A") increased by $0.4
million or 2.3% and $3.5  million or 7.6% for the third  quarter  and first nine
months of fiscal 2003,  respectively,  as compared to the same periods in fiscal
2002.  The increase in SG&A  expenses  compared to the prior year period was due
primarily to labor related expenses for increased  profit sharing,  increases in
commissions due to higher sales,  and the impact of fewer  shutdowns  during the
periods as explained  above.  The  increases in labor  expenses were offset by a
decrease in third quarter legal and publication expenses.

         Interest  income  was $9.5  million  and  $30.4  million  for the third
quarter and first nine  months of fiscal  2003,  a decrease of $3.0  million and
$11.0 million  respectively,  from the corresponding periods of fiscal 2002. The
interest  income earned on the increase in the Company's  cash  equivalents  and
short-term  investment  balance was more than offset by a decline in the average
interest rates from period to period.  The decrease in the interest rate was the
result of the Federal  Funds rate  dropping  from 1.75% in the third  quarter of
fiscal 2002 to 1.25% in the third quarter of fiscal 2003.

         The  Company's  effective tax rate for the third quarter and first nine
months of fiscal  2003 and 2002 was 29%.  The tax rate is  impacted  by business
activity in foreign  jurisdictions with lower tax rates and tax-exempt  interest
income.

Factors Affecting Future Operating Results

         Except for historical  information  contained  herein,  the matters set
forth in this Form 10-Q,  including the statements in the following  paragraphs,
are  forward-looking   statements  that  are  dependent  on  certain  risks  and
uncertainties  including such factors,  among others, as the timing,  volume and
pricing of new orders  received  and  shipped  during  the  quarter,  the timely
introduction  of new  processes and  products,  general  conditions in the world
economy and financial  markets and other factors described below and in our 10-K
for the fiscal year ended June 30, 2002.

         The quarter just completed was a strong quarter when compared with both
the previous  calendar quarter and the same quarter in the previous fiscal year.
The Company's  backlog coming out of the third quarter of fiscal 2003 is up from
the second quarter of fiscal 2003, although still low by historic standards, but
within a range  that the  Company  has  operated  under  in the past  year.  The
conditions  external to the Company remain largely unchanged,  as general global
economic  and  political  conditions  remain  causes  for  concern.   Therefore,
accurately   forecasting   short-term   future  results  is  difficult  in  this
environment. Looking forward, the June quarter is customarily a good quarter for
the Company.  Going into the quarter the Company has had good bookings  momentum
in all major  geographies  and all major  end-markets.  Business  has started to
improve in the USA again,  particularly  in some  communications  and industrial
applications.  Additionally,  the Company is well  positioned in new programs in
Asia,  primarily  in  cell  phone,  computer  and  high-end  consumer  products.
Consequently,  when weighing all the factors, including improving bookings, good
positioning in new programs, responsive lead time and inventory mix positioning,
returning strength in the USA and partially offsetting these positive factors by
customer  conservatism in response to worldwide economic  conditions,  political
concerns  and  travel  concerns  resulting  from the  SARS  virus,  the  Company
estimates that sales and profits in the current  quarter will grow in the mid to
high single digits, 5% to 8% from the March quarter.

                                       11



         Estimates of future performance are uncertain,  and past performance of
the Company may not be a good  indicator  of future  performance  due to factors
affecting  the Company,  its  competitors,  the  semiconductor  industry and the
overall  economy.   The   semiconductor   industry  is  characterized  by  rapid
technological  change,  price  erosion,   cyclical  market  patterns,   periodic
oversupply conditions,  occasional shortages of materials, capacity constraints,
variations  in  manufacturing  efficiencies  and  significant  expenditures  for
capital   equipment   and   product   development.   Furthermore,   new  product
introductions  and patent protection of existing  products,  as well as exposure
related to patent  infringement suits if brought against the Company are factors
that  can  influence  future  sales  growth  and  sustained  profitability.  The
Company's  headquarters  and a  portion  of  its  manufacturing  facilities  and
research  and  development   activities  and  certain  other  critical  business
operations  are  located  near  major  earthquake  fault  lines  in  California,
consequently,  the Company  could be adversely  affected in the event of a major
earthquake.

         Although  the  Company   believes  that  it  has  the  product   lines,
manufacturing  facilities and technical and financial  resources for its current
operations, sales and profitability could be significantly affected by the above
and other factors.  Additionally, the Company's common stock could be subject to
significant   price  volatility  should  sales  and/or  earnings  fail  to  meet
expectations of the investment community. Furthermore, stocks of high technology
companies  are subject to extreme price and volume  fluctuations  that are often
unrelated or disproportionate to the operating performance of these companies.

Liquidity and Capital Resources

         At March 30, 2003,  cash, cash  equivalents and short-term  investments
totaled $1,565.2 million, and working capital was $1,606.0 million.

         Accounts  receivable  totaled  $83.6  million  at the end of the  third
quarter of fiscal 2003,  an increase of $2.2 million from the fourth  quarter of
fiscal  2002.  The  increase  is  due to  higher  sales  offset  by  days  sales
outstanding (DSO) decreasing from the fourth quarter.

         Other assets  principally  relates to  technology  agreements  that are
generally amortized over their contractual periods, primarily 10 years using the
straight-line method of amortization.  The related liability for this technology
agreement is recorded as a long-term liability.

         Income  taxes  payable  totaled  $38.3  million at the end of the third
quarter of fiscal 2003 a decrease of $25.0  million  from the fourth  quarter of
fiscal 2002.  The decrease is the result of federal tax payments made during the
second and third quarter of fiscal 2003.

         During the first nine  months of fiscal  2003,  the  Company  generated
$189.8 million of cash from  operating  activities and $27.4 million in proceeds
from common stock issued under employee stock plans.

         During  the  first  nine  months  of  fiscal  2003,   significant  cash
expenditures included repurchasing $165.7 million of common stock, net purchases
of  short-term  investment  of  $61.5  million,  paying  $47.0  million  in cash
dividends to stockholders  representing $0.05 per share per quarter and spending
$5.2 million for the purchase of capital  assets.  In April 2003,  the Company's
Board of Directors  declared an increase in the quarterly cash dividend to $0.06
per share to be paid  during the June  quarter of fiscal  2003.  The  payment of
future dividends will be based on quarterly financial performance.

         As of March 30, 2003,  the Company had no off-balance  sheet  financing
arrangements or activities.

         Historically,  the Company has satisfied  its  liquidity  needs through
cash generated from operations and the placement of equity securities. Given its
strong financial  condition and  performance,  the Company believes that current
capital  resources  and  cash  generated  from  operating   activities  will  be
sufficient to meet its liquidity and capital  expenditures  requirements for the
foreseeable future.

Item 3.  Quantitative and Qualitative Disclosures About Market Risk

         For additional  quantitative and qualitative  disclosures  about market
risk  affecting  the Company,  see item 7A of the 10-K for the fiscal year ended
June 30, 2002.  There have been no material changes in the market risk affecting
the Company since the filing of the 10-K for fiscal 2002. At March 30, 2003, the
Company's  cash and  cash  equivalents  consisted  primarily  of bank  deposits,
commercial  paper and money market funds. The Company's  short-term  investments
consisted of municipal  bonds,  US  treasuries,  commercial  paper,  and federal
agency   securities.   The  Company  did  not  hold  any  derivative   financial
instruments.  The  Company's  interest  income is  sensitive  to  changes in the
general level of interest rates.  In this regard,  changes in interest rates can
affect  the  interest  earned  on  cash  and  cash  equivalents  and  short-term
investments.

Item 4.     Controls and Procedures

(a) Evaluation of disclosure controls and procedures

Within the 90-day period prior to the date of this report,  the Company  carried
out an  evaluation,  under the  supervision  and with the  participation  of the
Company's management,  including the Company's Chief Executive Officer and Chief
Financial  Officer,  of the  effectiveness  of the design and  operation  of the
Company's  disclosure  controls  and  procedures  pursuant to Rule 13a-14 of the
Securities   Exchange  Act  of  1934  (the  "Exchange  Act").  Based  upon  that
evaluation,  the Chief Executive  Officer and Chief Financial  Officer concluded
that the Company's  disclosure  controls and  procedures are effective in timely
alerting them to material  information  relating to the Company  (including  its
consolidated subsidiaries) required to be included in the Company's Exchange Act
filings.

(b) Changes in internal controls

There have been no significant  changes in the Company's internal controls or in
other factors,  which could significantly affect internal controls subsequent to
the date the Company carried out its evaluation.

                                       13



PART II.   OTHER INFORMATION


Item 1. Legal Proceedings

     As has been  previously  disclosed in the Company's  Form 10-K for the year
     ended June 30, 2002,  Texas  Instruments,  Inc. (TI) filed suit against the
     Company on January 6, 2001, in federal court in Texas alleging that certain
     semiconductor  manufacturing  equipment,  purchased  by  the  Company  from
     independent   third  party  suppliers  and  used  by  the  Company  in  its
     manufacturing  processes,  infringed  three  patents  owned  by TI (the "TI
     Patent  Suit").  On March 7, 2003, TI and the Company  agreed to settle all
     litigation pending between them,  including the TI Patent Suit, and entered
     into a ten year patent  portfolio  cross license  agreement.  The agreement
     also covers  manufacturing  equipment  purchased by the Company and used in
     its  manufacturing  process.  The agreement  calls for the Company to pay a
     royalty to TI over the license  term.  The  amortization  expense for these
     royalty  payments will not have a material  adverse effect on the Company's
     financial condition or results of operations.
