Upgrade to myMPS+Product Description
ultra low noise, low dropout and high PSRR linear regulator. The output voltage of MP20041 ranges from 1.2V to 3.6V in 100mV increments and 1% accuracy by operating from a +2.5V to +6.0V input. The MP20041 can supply up to 300mA of load current at each channel. The MP20041 uses an internal PMOS as the pass element, which consumes 114? 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 MP20041 features current limit and over temperature protection.
