MP2000-TPC10 5 TM MP2000 – LOW INPUT VOLTAGE, 150mA LINEAR REGULATOR INITIAL RELEASE SPECIFICATIONS SUBJECT TO CHANGE 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.
