描述 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.
