P7363
1.5A LOW QUIESCENT CURRENT, FAST TRANSIENT
ULTRA-LOW DROPOUT LINEAR REGULATOR
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, SOT223 and
TO252 packages.
