Microchip | MIC47100-12YMME-TR

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 2 mm × 2 mm MLF ® package with an operating junction temperature range of -40 °C to +125 °C.
