AP7341

300mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

Pin Assignments

The AP7341 is a 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 AP7341 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 AP7341 is well suited for low power handheld communication

equipment.

The AP7341 is packaged in an X2-DFN1010-4 package and allows

for smallest footprint and dense PCB layout.

PIN1 – V_OUT, PIN2 – GND, PIN3 – EN, PIN4 – V_IN
