Description

The AP7347D 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 AP7347D includes a voltage reference, error amplifier, currentlimit 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 AP7347D is well-suited for noise sensitive automotive equipment.

The AP7347D is packaged in the SOT25 (Type A1) and W-DFN2020-

6 (SWP) (Type A1) (wettable) packages, which allow for the smallest

footprint and a dense PCB layout.
