MIC3975 Micrel MIC3975 750mA µCap Low-Voltage Low-Dropout Regulator General Description The MIC3975 is a 750mA low-dropout linear voltage regulators that provide low-voltage, high-current output from an extremely small package. Utilizing Micrel’s proprietary Super βeta PNP™ pass element, the MIC3975 offers extremely low dropout (typically 300mV at 750mA) and low ground current (typically 6.5mA at 750mA). The MIC3975 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V or 3.0V, 3.3V to 2.5V or 2.5V to 1.8V or 1.65V. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC3975 to provide 2.5V from a supply as low as 3.0V and 1.8V or 1.65V from a supply as low as 2.25V.
