Low Dropout Linear Regulator
Pin Assignments
Description
The AP7335 is a 300mA, adjustable and fixed output voltage,
low dropout linear regulator. The device included pass
element, error amplifier, band-gap, current limit and thermal
shutdown circuitry. The device is turned on when EN pin is
set to logic high level.

The characteristics of low dropout voltage and low quiescent
current make it suitable for low power applications, for
example, battery powered devices. The typical quiescent
current is approximately 35μA. Built-in current-limit and
thermal-shutdown functions prevent IC from damage in fault
conditions.
