Features: MP20043 Dual Channel, 300mA Linear Regul ator With Programmable Output Voltage a nd Output Discharge DESCRIPTION The MP 20043 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 volt age options can be programmed by settin g the voltage of P1 and P2 to VDD, GND or floating. There are 9 different volt age settings in one chip. Each output c hannel can supply up to 300mA of load c urrent. The MP20043 uses two internal P MOSs as the pass devices, which consume s 150μA supply current when both chann els are enabled at no load condition. T he EN1 and EN2 pins control each output respectively. When both channels shutd own simultaneously, the chip turns off and consumes nearly zero operation curr ent which is suitable for battery-power devices. The MP20043 also features current limiting and over te.

MP20043
Dual Channel, 300mA Linear
Regulator With Programmable
Output Voltage and Output Discharge
DESCRIPTION
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.
It is available in a TQFN8 (2mm×2mm) package
