EN
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 2.2F 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 2.2F or greater capacitor.

MP2000 - LOW INPUT VOLTAGE, 150mA LINEAR REGULATOR
OPERATION
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. The MP2000 uses a PNP pass element and features internal thermal shutdown and an internal current limit circuit.

APPLICATION INFORMATION
Setting the Output Voltage The output voltage can be adjusted by changing the values of the external resistor divider. Use the following equation to determine these values:
R1 VOUT = 0.5 V x 1 + R2
Typically R1 + R2 are recommended to be less than 100k. In Figure 2, C2 is added for improved transient response.
