General Description 
The MIC5191 is an ultra high-speed linear regulator. It
uses an external N-Channel FET as its power device.
The MIC5191's ultra high-speed abilities can handle the
fast load demands of microprocessor cores, ASICs, and
other high-speed devices. Signal bandwidths of greater
than 500 kHz can be achieved with a minimum amount of
capacitance while at the same time keeping the output
voltage clean, regardless of load demand. A powerful
output driver delivers large MOSFETs into their linear
regions, achieving ultra-low dropout voltage.
1.25V
IN
 ?0% can be turned into 1V ?% without the use
of a large amount of capacitance.
MIC5191 (1.0V reference) is optimized for output voltages
of 1.0V and higher.
The MIC5191 is offered in 10-pin 3mm?mm MLF
?/DIV>
 and
10-pin MSOP-10 packages and has an operating junction
temperature range of 40癈 to +125癈.
