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.
