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.
