AP7343

300mA HIGH PSRR LOW NOISE LDO WITH ENABLE

Description

Pin Assignments

The AP7343 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.

(Bottom View)

The AP7343 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 AP7343 is well suited for low power handheld communication

equipment.

X2-DFN1010-4 (Type B)

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

The AP7343 is packaged in X2-DFN1010-4 (Type B) and SOT25

packages, allows for smallest footprint and dense PCB layout.
