Description

The AP7363 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 characteristics of low dropout voltage 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 IC from damage in fault conditions.

This device is available in U-DFN2030-8, SO-8EP and

SOT223-3L packages.
