The MP20045 is a low-dropout linear regulator supplies up to 1A current with 140mV dropout voltage. The output voltage is set externally which ranges from 1.5V to 5V by operating from +2.5V to +5.5V input or can be preset internally from 1.5V to 5V.
An internal PMOS pass element is used to allow a low 110μA ground current, making the MP20045 suitable for battery-power devices. Other features include low-power shutdown, short-circuit and thermal protection. The MP20045 is available in 8-pin QFN (3mm x 3mm) and SOIC8E packages.

EV20045DN-00A Evaluation Kit Low Noise, 1A, Linear Regulator EV Board
The EV20045DN-00A evaluation board demonstrates the performance of MP20045, a low noise and low dropout linear regulator. It operates from a 2.5V to 5.5V input voltage and the output voltage can be set externally which ranges from 1.5V to 5V.
The EV20045DN-00A can supply up to 1A of load current, and features current limiting, over temperature protection and power-good status.
An internal PMOS pass element is used to allow a low 110uA ground current, marking the MP20045 suitable for battery-power devices.
