MP20046DN-F-LF Monolithic Power Systems

MP20046 Fast Transient Response, 2A Low Dropout Voltage Regulator The Future of Analog IC Technology DESCRIPTION FEATURES Up to 2A Output Current The MP20046 is a low dropout linear regulator Low 210mV Dropout at 2A supplying up to 2A current with 210mV dropout voltage. The output voltage is preset internally Fast Transient Response which ranges from 1.5V to 3.3V. Open Drain Power-Good(PG) Status Output High 70dB at100Hz PSRR An internal PMOS pass element is used to Low 17V Output Noise RMS allow a low 75A ground current at full load and Current Limit and Thermal Protection drops down to 1uA when the device is disabled, Available in SOIC8 with Exposed Pad and making the MP20046 suitable for battery-power 10-pin QFN Packages devices. Integrated power good (PG) function resets microcomputer and microprocessor APPLICATIONS systems in the event of an under voltage Telecom condition. MP20046 are designed to have fast Servers response for larger load and line transient DSP, FPGA Supplies response. Other features include current limit and thermal protection.
