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.
