MIC5191 Micrel MIC5191 Ultra High-Speed, High-Current Active Filter/LDO Controller 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 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.
