Description

The AP7335A-50 is a 300mA, 5.0V 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.

This device is only available as a 5.0V fixed version. Please contact your local sales office for any other voltage options.

The AP7335A-50 is packaged in SOT25 and U-DFN2020-6.
