TO-220 Package
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.
