1 Amp Linear Regulator
General Description
Features
The AAT1117 is a Positive Linear Regulator
designed to deliver 1 amp. It features adjustable
or fixed output voltages and excellent
performance over line and load variations. The
device is able to protect itself and the load from
short circuit conditions with integrated current
limiting circuitry. Thermal shutdown is activated
to prevent damage under extreme conditions.
