Description

The AP7341 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 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.
