PIN FUNCTIONS
Pin # Name Description
1 IN
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.
2 GND Ground.
3
EN
Enable Input. Drive
EN high to turn off the MP2000; low to turn it on. For automatic startup,
connect
EN to GND.
4 FB
Feedback Input. Connect a resistive voltage divider from OUT to FB to set the output
voltage. OUT feedback threshold is 0.5V.
5 OUT
Regulator Output. OUT is the output of the linear regulator. Bypass OUT to GND with a
2.2μF or greater capacitor.
