P7340

150mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

The AP7340 is 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.

The AP7340 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 AP7340 is well suited for low power handheld communication

equipment.

The AP7340 is packaged in a X2-DFN1010-4 package and allows for

smallest footprint and dense PCB layout.
