AP7330

300mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

The AP7330 is a low dropout regulator with high output voltage

accuracy, low RDS(ON), high PSRR, low output noise and low

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

The AP7330 includes a voltage reference, error amplifier, current limit

circuit and an enable input to turn it on and off. With its low power

consumption and line and load transient response, the AP7330 is well

suited for low power handheld communication equipment.

The AP7330 is packaged in SOT25 package, allows for smallest

footprint and dense PCB layout.
