The MP20042 is a dual-channel, micropower, low noise, low dropout and high PSRR linear regulator. The output voltage of MP20042 ranges from 1.2V to 5.0V and 1% accuracy by operating from a +2.5V to +6.0V input. The MP20042 can supply up to 200mA of load current at each channel. The MP20042 uses an internal PMOS as the pass element, which consumes 114μA supply current (both LDOs on) at no load condition. The EN1 and EN2 pins control each output respectively. When both channels shutdown simultaneously, the chip will be turned off and consume nearly zero operation current which is suitable for battery-power devices. The MP20042 features current limiting and over temperature protection.
