AP7340: Miniature LDO Features High PSRR and Low Noise

The AP7340 is a CMOS low dropout regulator with high output voltage accuracy, low RDS(ON), high PSRR, low output noise and low quiescent current. With a high PSRR of 75dB at 1kHz and a low noise performance of 60µVRMS over the 10Hz to 100kHz range, the AP7340 ensures a high quality supply for analog circuits in noise sensitive audio, video and RF applications. Its integrated resistor network produces fixed output voltages in 0.1V steps between 1.2V and 3.3V.
