DESCRIPTION
The EV20045DQ-00A evaluation board
demonstrates the performance of MP20045, a
low noise, low dropout and high PSRR 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 EV20045DQ-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.
