The Future of Analog IC Technology
DESCRIPTION
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.
It is available in a 2mm x 2mm QFN8 package.
