Product 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.

Kit details

The EV20051DN-00A evaluation board demonstrates the performance of MP20051, a low noise and low dropout linear regulator. It operates from 2.5V to 5.5V input voltage and the output voltage can be set externally which ranges from 0.8V to 5V.

The EV20051DN-00A can supply up to 1A of load current, and features current limiting, over temperature protection.

An internal PMOS pass element is used to allow a low 110μA ground current, marking the MP20051 suitable for battery-power devices.
