Low Input Voltage 150mA Linear Regulator



The MP2000 is a low-voltage, low-dropout bipolar linear regulator. It operates from 1.35V to 6.0V input voltage, and regulates the output voltage from as low as 0.5V. The MP2000 can supply up to 150mA of load current. The MP2000 features thermal overload and current limit protection. It is available in a 5 pin TSOT23­5 package.
