MIC47050YML-TR

The MIC47050 is a high speed, ultra-low dropout (ULDO), dual supply NMOS regulator 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 500 mA of output current while only requiring a 1 μF ceramic output capacitor for stability. A 1.5% output voltage accuracy, low dropout voltage (44 mV at 500 mA) and low ground current make this device ideally suited for mobile and point-of-load applications. The MIC47050 has an NMOS output stage that offers very low output impedance. The NMOS output stage makes for a unique ability to respond very quickly to sudden load changes such as that 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 is available in fixed and adjustable output voltages in a tiny 2 mm×2 mm DFN and TDFN packages with an operating junction temperature range of -40°C to +125°C.
