AP7315

150mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

The AP7315 is a low dropout regulator with high output voltage

quiescent current. This regulator is based on a CMOS process.

The AP7315 includes a voltage reference, error amplifier, current limit

circuit and an enable input to turn it on and off. With the integrated

resistor network fixed output voltage versions can be delivered.

With its low power consumption and line and load transient response,

the AP7315 is well suited for low power handheld communication

equipment.

The AP7315 is packaged in X2-DFN1010-4, SOT23 and SOT25

packages and allows for smallest footprint and dense PCB layout.
