AP7342

DUAL 150mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

The AP7342 is a dual low dropout regulator with high output voltage

current. This regulator is based on a CMOS process.

Each regulator 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 AP7342 is well suited for low power handheld communication

equipment.

The AP7342 is packaged in X2-DFN1212-6 package and allows for

smallest footprint and dense PCB layout.
