3-TERMINAL POSITIVE ADJUSTABLE
REGULATOR
This monolithic integrated circuit is an adjustable 3-terminal
positive voltage regulator designed to supply 2.2A typical
of load current with an output voltage adjustable over a 1.2
to 37V. It employs internal current limiting, thermal shut-
down and safe area compensation.
