           Semtech Announces Third Quarter Conference Call;
                       Nasdaq Delisting Stayed


    CAMARILLO, Calif.--(BUSINESS WIRE)--Nov. 27, 2006--SEMTECH
CORPORATION (NASDAQ:SMTC), a leading supplier of analog and
mixed-signal semiconductors, today announced plans to release revenue
and other selected financial results for the third quarter of fiscal
year 2007 after the close of the market on Thursday, November 30,
2006. The results release will be available through Business Wire
(www.businesswire.com) and at the Company's website (www.semtech.com).

    As previously reported, the Company plans to restate its
historical financial statements to record additional non-cash
compensation expense related to stock option grants. The Company will
not be in a position to announce additional financial results for the
third fiscal quarter or file its Quarterly Report on Form 10-Q for the
period ended October 29, 2006 until the restated historical financial
statements have been filed with the Securities and Exchange
Commission.

    A Nasdaq Listing Qualifications Panel ("Panel") previously set
today as the deadline for the Company to file all required
restatements, its First Quarter Form 10-Q, and its Second Quarter Form
10-Q in order to regain compliance with Nasdaq's continued listing
standards. Today, the Company was notified that the Nasdaq Listing and
Hearings Review Council ("Listing Council"), in response to the
Company's request, has called the Panel's decision for review and has
stayed any future Panel determinations to suspend the Company's
securities from trading until the review process runs its course. If
the Listing Council determines it is appropriate, it may grant the
Company additional time to regain compliance, until the earlier of 60
days from the date of its decision or 180 days from the Panel's
decision. The Company continues to work diligently to file all
required reports with the SEC as quickly as possible and thereby
regain compliance with Nasdaq's listing requirements, but it can
provide no assurances that it will be able to do so. For additional
information regarding the pending restatement, see the Company's
Report on Form 8-K filed with the SEC on July 20, 2006.

    Semtech will host a conference call at 2:00 p.m. PT (5:00 p.m. ET)
on Thursday, November 30, 2006 to discuss third quarter performance
and events, current business activities and conditions, and the
outlook for the business. Investors and the interested public will
have the opportunity to listen to the conference call live over the
Internet by going to the investor relations section of Semtech's
website or to the following URL address:

    To listen to the live call, it is recommended that you go to the
Internet at least ten minutes early to download any necessary audio
software. For those who cannot listen to the live broadcast, beginning
later in the afternoon of November 30, 2006, a replay of the call will
be available at Semtech's website and the URL address shown above.

    Some statements made during the conference call may be
"forward-looking statements" related to matters such as future
financial performance, future operational performance, and plans,
objectives and expectations. Results could differ materially from
those projected in forward-looking statements due to factors
including, but not limited to, those set forth in the Company's latest
Form 10-K and other public filings with the Securities and Exchange
Commission. As set forth in the press release attached to the Form 8-K
filed by the Company on July 20, 2006, there are a number of risks
associated with matters related to the Company's historical stock
option practices. There is a risk that the Company may become
delinquent in filing future required reports and a risk that the
Company may not be able to file its restated financial statements and
delinquent reports in time to prevent Nasdaq delisting. Semtech
undertakes no duty to update any forward-looking statements, whether
as a result of new information, future events or otherwise.
