MIC5190
Ultra High-Speed, High-Current Active Filter/LDO Controller
General Description
The MIC5190 is an ultra high-speed linear regulator. It uses
an external N-Channel FET as its power device.
The MIC5190 offers ultra high-speed to cope with the fast
load demands of microprocessor cores, ASICs, and other
high-speed devices. Signal bandwidths of greater than 500kHz
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 0.9V ?% without the use of
a large amount of capacitance.
MIC5190 (0.5V reference) is optimized for output voltages of
below 1.0V.
The MIC5190 is offered in 10-lead 3mm ?3mm MLF" and
10-lead MSOP-10 packages and has an operating junction
temperature range of 40癈 to +125癈.
All support documentation can be found on Micrels web
site at www.micrel.com.
