LINEAR TECHNOLOGY REPORTS INCREASED SALES AND PRO FORMA PROFITS OVER THE SIMILAR
QUARTER IN THE PRIOR YEAR

     Milpitas,  California,  October 18,  2005,  Linear  Technology  Corporation
(NASDAQ-LLTC),  a leading,  independent  manufacturer of high performance linear
integrated circuits,  today announced that net sales for its first quarter ended
October  2,  2005,  were  $256,013,000,  an  increase  of 1% over  net  sales of
$253,028,000  for the first  quarter of the  previous  year.  The  Company  also
reported net income for the quarter of $99,181,000 or $0.31 diluted earnings per
share,  ($108,451,000  or $0.35 pro forma excluding stock based  compensation as
noted below) as compared to  $103,476,000  or $0.33  diluted  earnings per share
reported for the first  quarter of last year.  During the  quarter,  the Company
implemented   Financial   Accounting   Standard  123R  (FAS123R),   "Share-based
Payments",  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.
Since the  Company  began its fiscal year this  quarter,  it is one of the first
companies required to implement FAS123R. For Linear Technology, the total amount
of stock based compensation  during this quarter was $13,338,000.  Under FAS123R
calculations,   there  was  also  an  increase  in  estimated   diluted   shares
outstanding.  Consequently,  pro forma earnings per share, excluding stock based
compensation  accounting estimates,  would have been $0.35 for the quarter ended
October 2, 2005 versus $0.33 on a similar  basis for the prior  year's  quarter.
The Company's cash and short-term investments increased by $43.6 million, net of
spending  $64.5 million to purchase  1,656,165  shares of common  stock.  A cash
dividend of $0.10 per share will be paid on November 16, 2005 to stockholders of
record on October 28, 2005.

     According to Lothar  Maier,  CEO,  "Sequentially  sales were similar to the
June quarter,  however,  demand  increased  resulting in a positive book to bill
ratio. We continue to be strongly cash flow positive and our return on sales was
39% or 42% on a pro forma basis prior to the impact of stock based  compensation
accounting.

     Looking  ahead  to  the  December  quarter,  our  bookings  have  improved,
particularly in consumer related  products,  and consequently we expect sales to
increase, roughly in the 3% to 4% range."



     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.

     standards.


FAS123R - Stock  Based  Compensation  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 most companies have not yet adopted the provisions of FAS123R.
