AP7343Q

AUTOMOTIVE COMPLIANT 300mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

Pin Assignments

The DIODES™ AP7343Q is a low dropout regulator with high output

voltage accuracy, low R_DS(ON), high PSRR, low output noise and low

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

SOT25

V_IN

GND

V_OUT

The AP7343Q 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

responses, the AP7343Q is well suited for noise sensitive automotive

applications.
