Description
Power Source Input. IN supplies the internal power to the MP2000 and is the source of the
pass transistor. Bypass IN to GND with a 2.2µF or greater capacitor.
Ground.
Enable Input. Drive EN high to turn off the MP2000; low to turn it on. For automatic startup,
connect EN to GND.
Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output
voltage. OUT feedback threshold is 0.5V.
Regulator Output. OUT is the output of the linear regulator. Bypass OUT to GND with a
2.2µF or greater capacitor.

OPERATION
The MP2000 uses a PNP pass element and
features internal thermal shutdown and an
internal current limit circuit.
The MP2000 is a low-current, low-voltage,
low-dropout linear regulator. It is intended for
use in devices that require very low voltage and
low quiescent current power such as wireless
modems, pagers and cellular phones.
