DESCRIPTION
The EVQ20051-Q-00A evaluation board
demonstrates the performance of MPQ20051, 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 EVQ20051-Q-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 110A ground current, marking the
MPQ20051 suitable for battery-power devices.
