概要

The MP20142 is a dual-channel, low noise, low dropout and high PSRR linear regulator with programmable output voltage. The output voltage of MP20142 ranges from 1.2V to 3.3V in 100mV increments and 2.5% accuracy by operating from a +2.5V to +5.5V input. The different output voltage options can be programmed by setting the voltage of P1 and P2 to VDD, GND or floating. There are 9 different voltage settings in one chip. Each output channel can supply up to 200mA of load current. The MP20142 uses two internal P-channel MOSFETs as the pass devices, which consumes 150μA supply current when both channels are enabled at no load condition. The EN1 and EN2 pins control each output respectively. When both channels shutdown simultaneously, the chip turns off and consumes nearly zero operation current which is suitable for battery-power devices. The MP20142 also features current limiting, output discharge and over temperature protection.
