LINEAR TECHNOLOGY  REPORTS INCREASED  QUARTERLY SALES AND PROFITS OVER THE PRIOR
YEAR'S QUARTER AND INCREASES ITS QUARTERLY CASH DIVIDEND FROM $0.08 TO $0.10 PER
SHARE.


         Milpitas,  California,  January 18, 2005, Linear Technology Corporation
(NASDAQ-LLTC),  a leading,  independent  manufacturer of high performance linear
integrated circuits, today announced that net sales for its second quarter ended
January  2,  2005,  were  $250,121,000,  an  increase  of 34% over net  sales of
$186,021,000  for the second  quarter of the  previous  year.  The Company  also
reported net income for the quarter of  $102,818,000  or $0.33 diluted  earnings
per share,  an increase of 38% from  $74,335,000  or $0.23 diluted  earnings per
share  reported for the second  quarter of last year.  During the  quarter,  the
Company's cash and  short-term  investments  increased by $27.3 million,  net of
spending $54.7 million to purchase 1,500,000 shares of common stock.

         The Company  increased its  quarterly  dividend from $0.08 to $0.10 per
share.  The payment will be made on February 16, 2005 to  stockholders of record
on January 28, 2005.

         According to Lothar Maier, CEO, "As expected, sales and net income were
slightly down from the September  quarter.  However the Company  continued to be
cash flow  positive  and strongly  profitable  as evidenced by the 41% return on
sales.  Bookings improved slightly during the quarter,  particularly late in the
quarter. Our ending on-hand inventory at distributors is lean; cancellations are
still minimal; and, lead times have remained unchanged at 4 to 6 weeks.

         These  continue  to be  challenging  times  to  forecast.  Softness  in
bookings  for   semiconductor   companies  has  resulted  from  both   inventory
corrections  throughout the various sales channels and also some  moderations in
the rate of growth of end demand. Looking forward to the March quarter we do not


expect further inventory  reductions in the sales chain,  rather bookings in the
March quarter will be more reflective of true end-user consumption  patterns. We
expect end demand to be relatively stable, with bookings  increasing  moderately
over the prior  quarter.  Consequently,  we  expect  sequential  revenues  to be
similar to the quarter just ended."

         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 June
27, 2004.

         Company officials will be discussing these results in greater detail in
a conference  call tomorrow,  Wednesday,  January 19, 2005 at 8:30 a.m.  Pacific
