MICROCHIP MIC5190YMM

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. 1.25Vin⁺¹⁰% can be turned into 0.9V±1% without the use of a large amount of capacitance. MIC5190₍₀.₅iₒᵣ₎ reference is optimized for output voltages of below 1.0V.
