The Future of Analog IC Technology
MP20051
Low Noise, High PSRR, 1A
Linear Regulator
DESCRIPTION
The MP20051 is a low-dropout linear regulator
that supplies up to 1A current with a 140mV
dropout voltage. The externally-adjustable output
voltage has a range of 0.8V to 5V from an input
voltage of 2.5V to 5.5V.
An internal PMOS pass element allows for a low
110μA ground current, making the MP20051
suitable for battery-powered devices. Other
features include low-power shutdown, and short-
circuit and thermal protection. The MP20051 is
available in 3mm x 3mm 8-pin QFN and SOIC8E
packages.
