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, TO252-3L and SOT223-3L packages.
