Exhibit 99.1

Semtech Announces Strong Third Quarter Results

    CAMARILLO, Calif.--(BUSINESS WIRE)--Nov. 24, 2003--

                New Orders Up 23 Percent Sequentially;
                  Net Sales and EPS Exceed Forecast;
      Outlook for 8 to 10 Percent Sales Growth in Fourth Quarter

    Semtech Corporation (Nasdaq:SMTC), a leading producer of high
performance analog and mixed-signal semiconductors, today announced
that net sales for its third quarter of fiscal year 2004 increased 8
percent compared to the second quarter. This exceeded the Company's
prior forecast. Gross margin, operating income and earnings per share
for the quarter also improved ahead of forecast.
    Net sales for the third quarter that ended October 26, 2003 were
$48.1 million, up from $44.6 million in the second quarter and $47.2
million in the prior year third quarter. Net income for the third
quarter of fiscal year 2004 was $9.3 million or 12 cents per diluted
share.
    Gross margin was 58.0 percent in the third quarter of fiscal year
2004, up from 57.3 percent in the second quarter and 56.0 percent in
the prior year period. Third quarter operating income increased 26
percent over the previous quarter and 30 percent compared to the prior
year quarter. The increase in operating income reflected improved
sales and increased contribution from higher margin products.
    Net sales for the first nine months of fiscal year 2004 were
$136.7 million and net income was $19.9 million or 26 cents per
diluted share. For the first nine months of fiscal year 2003, net
sales were $148.4 million and net income was $34.1 million or 44 cents
per diluted share. Interest and other income/expense for both nine
month periods include gains related to the Company's repurchase of
convertible subordinated debentures. The first nine months of the
current fiscal year include the expense of calling the remaining
outstanding convertible subordinated debentures.
    New orders in the third quarter of fiscal year 2004 increased 23
percent compared to the prior quarter. This resulted in the Company's
highest quarterly book-to-bill ratio in the last 4 years and best
order volume since the fourth quarter of fiscal year 2001. Demand was
particularly strong for Power Management products used in notebook
computers, cellular handsets and other handheld devices.
    Jason Carlson, Semtech's President and Chief Executive Officer,
commented, "Our performance in portable applications has been
outstanding. Building off our strength in Power and Protection, we are
now starting to win designs for Human Input Devices (HID) used to
control touch-pads, pointing sticks and keyboards. Improved demand for
products used in more capital intensive end-markets, like test,
industrial and communication systems are also driving sales growth and
higher gross margin."
    Two of Semtech's emerging product lines recorded impressive order
growth during the quarter. Orders for the Company's SETS and
Networking/Industrial Power Management product lines both grew
sequentially in excess of 35 percent. In addition, an initial design
win for HID products was recorded with a major notebook OEM. These
three emerging product lines contribute to Semtech's outlook for sales
growth and margin expansion over the coming year.

    Fourth Quarter Outlook

    Based on beginning backlog entering the quarter, Semtech estimates
that net sales for the fourth quarter of fiscal year 2004 will be up 8
to 10 percent over the third quarter. Turns orders (orders received
and shipped in the same quarter) of approximately 35 percent are
required to achieve this forecast. Gross margin and operating income
should improve. Earnings per diluted share in the fourth quarter are
forecasted to be 14 cents.
    Mr. Carlson added, "As the end-markets have improved, our customer
base has begun to give us more visibility. This has allowed us to
build some backlog, which has reduced our reliance on turns orders to
below 50 percent for the first time in three quarters."
    Semtech spent $3.1 million on the repurchase of common stock in
the third quarter and expects to continue to buyback shares under its
current buyback program. The Company ended the third quarter with
$260.3 million of cash and investments, up $14.5 million from the
prior quarter.
