MP8904DD-LF-P Monolithic Power Systems

MP8904 500mA Linear Regulator The Future of Analog IC Technology DESCRIPTION FEATURES The MP8904 is a low-current, low-dropout, Power-Good Open Collector Output linear regulator that operates on a single 2.5V- Operates from a 2.5V-to-6.5V Input to-6.5V input supply. An external resistor Low 300mV Dropout at 500mA Output controls the output voltage. The MP8904 can Stable with Very Small Ceramic Capacitors supply up to 500mA of load current. The enable 2% Feedback Reference pin (EN) allows the part to enter a low-current Adjustable Output Voltage from 0.5V to 5V shutdown mode (EN=0). The MP8904 features Better than 0.001%/mA Load Regulation thermal overload and current limit protection. It Stable with Low-ESR Output Capacitor is available in an 8-pin QFN (23mm) package. Low 100 A Ground Current Internal Thermal Protection Current Limit Protection 6A Typical Quiescent Current at Shutdown APPLICATIONS Low-Current Regulators Battery-Powered Systems Mobile Devices, such as Cell Phones and GPS Navigators All MPS parts are lead-free and adhere to the RoHS directive.

(2) 2) The maximum allowable power dissipation is a function of the Continuous Power Dissipation (T = +25C) A maximum junction temperature T(MAX), the junction-to- J .2.5W ambient thermal resistance , and the ambient temperature JA T . The maximum allowable continuous power dissipation at A Junction Temperature...............................150C any ambient temperature is calculated by P (MAX)=(T (MAX)- D J T )/ . Exceeding the maximum allowable power dissipation A JA Lead Temperature ....................................260C will cause excessive die temperature, and the regulator will go Storage Temperature .............. -65C to +150C into thermal shutdown. Internal thermal shutdown circuitry (3) protects the device from permanent damage. Recommended Operating Conditions 3) The device is not guaranteed to function outside of its operating conditions.
