Micrel MIC47050
The MIC47050 is a high-speed, ultra-low dropout, dualsupply 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. The MIC47050 has an NMOS output stage offering very low output impedance.GENERAL DESCRIPTION
A 1.5% output voltage accuracy, low dropout voltage (44mV @ 500mA), and low ground current makes this device ideally suited for mobile and point-of-load applications. 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 therefore 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 the tiny 2mm x 2mm MLF® and Thin MLF® packages with an operating junction temperature range of 40C to 125C.
