MIC5190

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±10% can be turned into 0.9V ±1% 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 3mmx3mm MLF and 10-lead MSOP-10 packages and has an operating junction temperature range of –40°C to +125°C.
