Summary

The MIC47050 is a high-speed, ultra-low dropout, dual-supply NMOS ULDO™ designed to take advantage of point-of-load applications that use multiple supply rails to generate a low-voltage, high-current power supply. The MIC47050 can source 500mA of output current while only requiring a 1μF ceramic output capacitor for stability. A 1.5% output voltage accuracy, low dropout voltage (44mV @ 500mA), and low ground current makes this device ideally suited for mobile applications.
