AP7344

DUAL 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

Pin Assignments

The AP7344 is a Dual low dropout regulator with high output voltage

accuracy, low R_DSON, high PSRR, low output noise and low quiescent

current. This regulator is based on a CMOS process.

Each of regulators includes a voltage reference, error amplifier,

current limit circuit and an enable input to turn on/ off output. With the

integrated resistor network fixed output voltage versions can be

delivered.

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

the AP7344 is well suited for low power handheld communication

equipment.

The AP7344 is packaged in X2-DFN1612-8 package and allows for

smallest footprint and dense PCB layout.
