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 at 500mA), and low ground current makes this device ideally suited for mobile and point-of-load applications.
The MIC47050 has an NMOS output stage offering very low output impedance. The NMOS output stage makes for a unique ability to respond very quickly to sudden load changes such as those required by a microprocessor, DSP or FPGA. The MIC47050 consumes little quiescent current and can be used for driving the core voltages of mobile processors, post regulating a core DC/DC converter in any processor.
The MIC47050 operates over a junction temperature range of -40°C to +125°C.
The MIC47050 now offers automotive grade 1. AEC-Q100 and PPAP capable.
