Description

The AP7347EQ is a low-dropout regulator with high output-voltage accuracy, low RDS(ON), high PSRR, low output noise, and low quiescent current. This regulator is based on a CMOS process.

The AP7347EQ 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 version and adjustable output-voltage version can be delivered. The AP7347EQ has power-good indicator.

With its low power consumption and line- and load-transient response, the AP7347EQ is well-suited for noise-sensitive automotive equipment.

The AP7347EQ is packaged in the U-DFN2020-6 (SWP) (Type UXC) and V-DFN3030-8/SWP (Type UX) packages.
