Description
This monolithic integrated circuit is an adjustable 3-termi-
nal positive-voltage regulator designed to supply more
than 1.5 A of load current with an output voltage adjust-
able over a 1.2 V to 37 V range. It employs internal cur-
rent limiting, thermal shutdown, and safe area
compensation.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is 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.
