DiodesZetex AP7347DQ-18FDZW-7B, 1 Low Dropout Voltage, Voltage Regulator 500mA, 5 V

The DiodesZetex 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. This 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, this device is well-suited for low power handheld automotive
equipment.

Ripple rejection 75dB at 1kHz
Halogen and antimony free green device
