Description

The AP7347E 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.

The AP7347E 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 and adjustable output voltage version can be delivered. The AP7347E has power good indicator.

With its low power consumption and line and load transient response, the AP7347E is well-suited for noise sensitive equipment.

The AP7347E is packaged in the U-DFN2020-6 (SWP) (Type UXC) and V-DFN3030-8/SWP (Type UX) packages
