LINEAR TECHNOLOGY REPORTS INCREASED REVENUES AND PROFITS OVER THE PRIOR QUARTER.

     Milpitas,   California,  April  18,  2006,  Linear  Technology  Corporation
(NASDAQ-LLTC),  a leading,  independent  manufacturer of high performance linear
integrated  circuits,  today announced that total revenues for its third quarter
ended April 2, 2006,  of  $278,888,000,  increased 5% over second  quarter total
revenues of  $265,146,000.  The Company  also  reported  that third  quarter net
income of $110,555,000,  or $0.35 diluted earnings per share,  increased 7% over
second quarter net income of $103,264,000  or $0.33 diluted  earnings per share.
Sequentially,  the Company's cash and short-term  investments increased by $74.1
million,  net of spending  $20.2  million to purchase  532,769  shares of common
stock.  A cash  dividend  of $0.15  per  share  will be paid on May 17,  2006 to
stockholders of record on April 28, 2006.

     On a  year-over-year  basis,  fiscal 2006 third quarter  total  revenues of
$278,888,000  decreased  4% from total  revenues of  $290,734,000  for the third
quarter of the previous year.  Included in last year's quarterly  revenues was a
royalty payment of $40,000,000,  which represented past royalties under terms of
a settlement and license  agreement with another company.  Subsequent  quarterly
royalty  payments  have  been  immaterial  to each  individual  quarter's  total
revenues.  Net income for the quarter of $110,555,000 or $0.35 diluted  earnings
per  share,  ($119,742,000  or $0.38 per share pro forma  excluding  stock-based
compensation  as noted below)  decreased 9% as compared to $121,633,000 or $0.39
diluted earnings per share  ($126,562,000 or $0.40 per share pro forma) reported
for the third  quarter  of last year.  Net income for the third  quarter of last
year was also positively affected by the $40,000,000 royalty payment.

     During  this fiscal  year,  the Company  implemented  Financial  Accounting
Standard No. 123R (FAS123R),  "Share-based Payment," which requires companies to
estimate  the cost of all forms of  stock-based  compensation,  including  stock
options,  restricted  stock and  employee  stock  purchase  plans,  and record a
commensurate expense in their income statement. For Linear Technology, the total
amount of stock-based  compensation  during this quarter was $13,218,000.  Under
FAS123R  calculations,  there was also an increase in estimated  diluted  shares
outstanding.  Consequently,  pro forma  diluted  earnings  per share,  excluding
stock-based  compensation  accounting  estimates,  would have been $0.38 for the
quarter ended April 2, 2006 versus $0.40 on a similar basis for the prior year's
quarter.



     According to Lothar  Maier,  CEO,  "Sales and profits for the March quarter
increased sequentially from the December quarter.  Demand increased resulting in
a positive book to bill ratio. Our return on sales was a strong 40%, or 43% on a
pro forma basis prior to the impact of stock-based compensation accounting,  and
we continue to be cash flow positive.

     As we had anticipated,  strong sales for domestic and European distributors
signaled a solid  improvement in our broad based  industrial  business.  Looking
ahead,  we  currently  expect this to continue  into the June quarter and we are
expecting sales and profits to again increase roughly 5%."

     Except for historical  information  contained herein, the matters set forth
in this  press  release  are  forward-looking  statements.  In  particular,  the
statements  regarding  the  demand for our  products,  our  customers'  ordering
patterns and the anticipated growth of our sales and profits are forward-looking
statements.  The  forward-looking  statements are dependent on certain risks and
uncertainties,  including such factors,  among others, as the timing, volume and
pricing of new orders  received  and  shipped,  the timely  introduction  of new
processes  and products,  general  conditions in the world economy and financial
markets and other  factors  described in our 10-K for the fiscal year ended July
3, 2005.

     Company  officials will be discussing  these results in greater detail in a
conference call tomorrow,  Wednesday,  April 19, 2006 at 8:30 a.m. Pacific Coast

(1) Excludes 1,958 and 1,943 shares for the three and nine months ended April 2,
2006,  respectively,  to conform diluted  outstanding  shares  calculated  under
FAS123R to diluted shares calculated under prior accounting standards


FAS123R - Share-Based  Payment  became  effective and was adopted by the Company
during the  quarter  ended  October 2, 2005.  FAS123R  requires  the  Company to
estimate the cost of all forms of stock-based  compensation,  including employee
stock options, and to record a commensurate expense in the income statement.  To
supplement our consolidated  financial  statements  presented in accordance with
GAAP, we have shown above a non-GAAP (pro forma)  presentation  of the Company's
earnings per share, which is adjusted to reflect the GAAP results to exclude all
stock-based  compensation.  This non-GAAP  presentation of earnings per share is
provided to enhance the user's overall understanding of the Company's historical
financial performance and comparability between periods. We believe the non-GAAP
results  provide  useful  information  to  investors  by  excluding  stock-based
compensation  particularly  during this transitional  period when many companies
are initially adopting the provisions of FAS123R.
