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 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.
1.25VIN ±10% can be turned into 1V ±1% 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-lead 3mm x 3mm MLF® and 10-lead MSOP-10 packages and has an operating junction temperature range of -40°C to +125°C.
