GENERAL DESCRIPTION
The AS29372 is an efficient voltage regulator with very low
dropout voltage and very low quiescent current. Key features
include protection against reversed battery, fold-back current
limiting, and automotive “load dump” protection. A logic
compatible input is provided, which allows the device to be
switched on and off.
