MP20045 Low Noise, 1A Linear Regulator The Future of Analog IC Technology DESCRIPTION FEATURES The MP20045 is a low-dropout linear regulator supplies up to 1A current with 140mV dropout voltage. The output voltage is set externally which ranges from 1.5V to 5V by operating from +2.5V to +5.5V input or can be preset internally from 1.5V to 5V. • • • • An internal PMOS pass element is used to allow a low 110µA ground current, making the MP20045 suitable for battery-power devices. Other features include low-power shutdown, short-circuit and thermal protection. The MP20045 is available in 8-pin QFN (3mm x 3mm) and SOIC8E packages. • • • • • Up to 1A Output Current Low 140mV Dropout at 1A Low 110µA Ground Current Fixed Output Versions Ranging from 1.5V to 5V and Adjustable Versions Open Drain Power-Good Status Output 13µVRMS Low Noise Output 56dB PSRR at 1kHz Current Limiting and Thermal Protection 3mm×3mm QFN8 and SOIC8E Packages APPLICATIONS • • • • • • Notebook Computers Cordless Telephones Cellular Phones Modems Hand-Held Instruments PDA and Palmtop Computers “MPS” and “The Future of Analog IC Technology” are Registered Trademarks of Monolithic Power Systems, Inc.
