The MIC47050 is a high-speed, ultra-low dropout, dual-supply NMOS ULDO designed for point-of-load applications using multiple supply rails. It can source 500mA of output current while only requiring a 1µF ceramic output capacitor for stability. Its low dropout voltage (44mV @ 500mA), low ground current, and fast transient response make it suitable for mobile and point-of-load applications, DSP, PLD and FPGA power supply, and low-voltage post regulation.
