MIC47100
1A High Speed Low VIN LDO
General Description
The MIC47100 is a high speed, Low V IN 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.
