AP7347D 500mA HIGH PSRR LOW NOISE LDO WITH ENABLE 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. Pin Assignments (Top View) VIN 1 5 VOUT 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. GND 2 EN 3 4 NC With its low power consumption and line and load transient response, the AP7347D is well-suited for noise sensitive automotive equipment.
