Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers

will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor

product management systems do not have the ability to manage part nomenclature that utilizes an underscore

(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain

device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated

device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

email any questions regarding the system integration to Fairchild_questions@onsemi.com.

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 and s tres si ng the parts to these level s i s not recommended. 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.

13. To specify an output volt age, sub stitute volt age val ue 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.
