Technical coantmesntAsGtill valid Datasheet AS1374 Dual 200mA, Low-Noise, High-PSRR, Low Dropout Regulators 1 General Description The AS1374 is a low-noise, low-dropout linear regulator with 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 (30µA). The AS1374 uses an advanced architecture to achieve ultra-low output voltage noise of 20µVRMS and a power-supply rejection-ratio of better than 85dB (@ 1kHz).
