MP20043

Dual Channel, 300mA Linear

Regulator With Programmable

Output Voltage and Output Discharge

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP20043 is a dual-channel, low noise, low

dropout and high PSRR linear regulator with

programmable output voltage. The output

voltage of MP20043 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 300mA of load

current.

The MP20043 uses two internal PMOSs 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

MP20043 also features current limiting and over

temperature protection.
