AP7362
1.5A, LOW QUIESCENT CURREENT, FAST TRANSIENT
ULTRA-LOW DROPOUT LINEAR REGULATOR
Description
The AP7362 is a 1.5A adjustable output voltage linear regulator with
ultra-low dropout. The device includes pass element, error amplifier,
band-gap, current limit and thermal shutdown circuitry. The integrated
Enable block allows the part to be turned on and off via a logic signal.
A logic high level on EN turns the device on and a logic low turns the
part off.
The low dropout voltage characteristics and fast transient response to
step changes in load make it suitable for low voltage microprocessor
applications. The typical quiescent current is approximately 0.5mA
and changes little with load current. The built-in current-limit and
thermal-shutdown functions prevent damage to the IC in fault
conditions.
This device is available in U-DFN2030-8 and SO-8EP packages.
