Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-

ble above the re co mmen ded operating conditions an d s tres sing the parts to the se lev el s i s n ot re co mme nde d. In addi-

tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The

absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.

Notes:

13. To specify an ou tput volt age, sub stitute volt age value for “XX”.

14. CI is required if the regulator is located an appreciable distance from the power supply filter. Though Co is not

needed for stabil ity, it improves transient res ponse. Bypas s capacitors a re recommended for optimum stab ility and

transient response and should be located as close as possible to the regulator.

AUTHORIZED USE

Unless otherwise specified in this data sheet, this product is a standard commercial product and is not intended for use in applications that require extraordinary

levels of quality and reliability. This product may not be used in the following applications, unless specifically approved in writing by a Fairchild officer: (1) automotive

or other transportation, (2) military/aerospace, (3) any safety critical application – including life critical medical equipment – where the failure of the Fairchild product

reasonably would be expected to result in personal injury, death or property damage. Customer’s use of this product is subject to agreement of this Authorized Use

policy. In the event of an unauthorized use of Fairchild’s product, Fairchild accepts no liability in the event of product failure. In other respects, this product shall be

ANTI-COUNTERFEITING POLICY

Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com,

under Terms of Use

Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their

parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed

applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the

proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild

Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors

are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical

and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise.

Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global

problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
