MIC47100YMME

The MIC47100 is a high speed, Low VIN LDO capable of delivering up to 1A and designed to take advantage of point of load applications that use multiple supply rails to generate a low voltage, high current power supply. The MIC47100 is stable with only a 1μF ceramic output capacitor and is available in a thermally enhanced 2mm × 2mm MLF package thus making it an optimal solution for board-constrained applications. The MIC47100 has an NMOS output stage offering very low output impedance. The NMOS output stage offers a unique ability to respond very quickly to sudden load changes such as that required by a microprocessor, DSP or FPGA. The MIC47100 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 portable device. The MIC47100 is available in fixed and adjustable output voltages in the exposed pad MSOP-8 package and the tiny 2mm × 2mm MLF package with an operating junction temperature range of -40°C to +125°C.
