(Top View)
The AP7335A is a 300mA, fixed output voltage, low-dropout linear
regulator with ±1% output voltage accuracy. The device includes
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 35μA. Built-in,
current-limit and thermal-shutdown functions prevent IC from damage
in fault conditions.
