MP2002DD-LF-Z Monolithic Power Systems

MP2002 Low Input Voltage 500mA Linear Regulator NOT RECOMMENDED FOR NEW DESIGNS DESCRIPTION FEATURES Power Good Open Collector Output The MP2002 is a low-current, low-dropout Operates from 1.35V 6.5V Input linear regulator operating over a single input supply between 1.35V to 6.5V. The output Low 300mV Dropout at 500mA Output voltage of the MP2002 is adjustable via an Stable with Very Small Ceramic Capacitors external resistor divider. The MP2002 can 2% Feedback Reference supply up to 500mA of load current. The enable Adjustable Output Voltage Option from 0.5V pin (EN) allows the part to be put into a low to 5V using an External Resistor Divider current shutdown mode (EN=0). The MP2002 Better Than 0.001%/mA Load Regulation features thermal overload and current limit Low 100A Ground Current protection. It is available in an 8-pin QFN (2 x Internal Thermal Protection 3mm) package Current Limit Protection 6A Typical Quiescent Current at Shutdown Available in a Tiny 2 x 3mm 8-pin QFN Package APPLICATIONS Low Current Regulators Battery Powered Systems Cellular Phones For MPS green status, please visit MPS website under Quality Assurance.
