NEW PRODUCT

Description

The AP7335A is a 300mA, 5.0V fixed output voltage, low

dropout linear regulator with ±1% output voltage accuracy.

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 35μA. Built-in current-limit and thermal-shutdown

functions prevent IC from damage in fault conditions.

This device is only available as 5.0V fixed version. Please

contact your local sales office for any other voltage options.

The AP7335A is packaged in SOT25 and U-DFN2020-6.
