DESCRIPTION

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.
