General Description

The MIC47100 is a high speed, Low V

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

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.

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

temperature range of -40°C to +125°C.
