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.
