DESCRIPTION

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.
