DESCRIPTION
The EV20046DQ-00A evaluation board
demonstrates the performance of MP20046, a
low noise, low dropout and high PSRR linear
regulator. It operates from a 2.7V to 5.5V input
voltage and the output voltage is preset
internally which ranges from 1.5V to 3.3V.
The EV20046DQ-00A can supply up to 2A 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 75μA ground current at full load,
and drops down to 1μA when the device is
disabled, making the MP20046 suitable for
battery-power devices.
