Exhibit 99.1


                Semtech Announces First Quarter Results


    CAMARILLO, Calif.--(BUSINESS WIRE)--May 27, 2003--Semtech
Corporation (Nasdaq:SMTC) today announced results for its fiscal year
2004 first quarter that ended April 27, 2003.
    Sales for the first quarter of fiscal year 2004 were $44.0 million
and net income was $8.3 million or 11 cents per diluted share. Sales
for the first quarter of fiscal year 2003 were $49.2 million and net
income was $10.0 million or 13 cents per diluted share. Gross margin
was 56.5 percent in the first quarter of fiscal year 2004, compared to
56.2 percent in the prior quarter and 57.1 percent in the prior year
first quarter. Sales for the fourth quarter of fiscal year 2003 were
$44.5 million and net income was $62,000.
    Semtech continued to strengthen its balance sheet. Long-term debt
was reduced by $59.5 million during the first quarter of fiscal year
2004. Cash and marketable securities, net of outstanding debt,
increased to $248.3 million. Annualized inventory efficiencies
improved to 5.2 turns of inventory per year as of the first quarter.
    The Company has bought back $250.0 million in convertible
subordinated notes and common stock under its current buyback program,
and has remaining $25.0 million authorized for additional purchases.
In the first quarter of fiscal year 2004, the Company recorded a $2.8
million pre-tax gain on the repurchase of convertible subordinated
notes.
    Shipments of all product lines, except for Test and Measurement
and Desktop Power Management, increased sequentially in the first
quarter of fiscal year 2004. Portable Power Management sales were up
11 percent sequentially and up 136 percent compared to the prior year
period. Protection Product sales in the first quarter were up 9
percent from the prior quarter and Advanced Communications product
sales were up 27 percent.
    New orders in the first quarter of fiscal year 2004 were up
slightly over the prior quarter. The largest percentage increases were
in the Test and Measurement and Human Input Device (HID) product
lines. The largest decline in new orders was in Desktop Power
Management, reflecting lower demand from the computer gaming segment
and delays in new desktop designs. Orders from desktop computer
customers are forecasted to improve toward the end of the second
quarter, as Semtech begins to benefit from increased market-share in
next generation systems.
    Jack Poe, Semtech's Chairman and CEO, commented, "Sales of
products used in portable applications remained strong in the first
quarter and were up over 105 percent compared to the prior year. In
particular, our market-share in powering notebook computers and color
screens in cellular phones has increased substantially. First quarter
results were negatively impacted by seasonal weakness and average
selling price declines in products sold into the desktop computer
market. Sales to computer gaming and automated test equipment (ATE)
customers were also weak."
    Mr. Poe added, "New orders were at their highest level in the past
four quarters and suggest there will be improved growth opportunities
in the second half of fiscal year 2004. We expect continued strength
in portable applications and improvements in the desktop, ATE and
telecom end-markets to begin late in the second quarter."
    The expected improvement in second half conditions is broad based,
including assumed higher rates of growth from several newer product
lines. Semtech's highly proprietary SETS product line, used for timing
and synchronization in high-end networking systems, is benefiting from
design wins secured in the last two years. Semtech's industry leading
HID technology is gaining traction at several major OEMs. Finally, the
Networking/Industrial Power Management product line secured 33 new
design wins in the first quarter, including designs with power supply
makers which support broad end-applications.
    Semtech estimates that net sales for the second quarter of fiscal
year 2004 will be flat to up 2 percent from the first quarter. Turns
orders (orders received and shipped in the same quarter) of
approximately 51 percent are required to achieve this forecast. Gross
margin and operating income are forecasted to improve. Interest and
other income will be down in the coming quarter due to lower rates of
return on investments and the expected absence of gain on the
repurchase of convertible subordinated notes. Earnings per diluted
share are forecasted to be either 9 or 10 cents in the second quarter.
