DESCRIPTION
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.
It is available in a TQFN8 (2mm×2mm) package.
