AS1374 Dual 200mA, Low-Noise, High-PSRR, Low Dropout Regulator The AS1374 is a low-noise, low-dropout linear regulator with General Description two separated outputs. Designed to deliver 200mA continuous output current at each output pin, the LDOs can achieve a low 120mV dropout for 200mA load current and are designed and optimized to work with low-cost, small-capacitance ceramic capacitors. An integrated P-channel MOSFET pass transistor allows the devices to maintain extremely low quiescent current (30A). The AS1374 uses an advanced architecture to achieve ultra-low output voltage noise of 20VRMS and a power-supply rejection-ratio of better than 85dB ( 1kHz). Two active-High enable pins allows to switch on or off each output independently from each other. The AS1374 requires only 1F output capacitor for stability at any load. The device is available in a 6-bump WLCSP package. Ordering Information and Content Guide appear at end of datasheet.
