MIC3975
General Description
The MIC3975 is a 750mA low-dropout linear voltage regula-
tors that provide low-voltage, high-current output from an
extremely small package. Utilizing Micrel’s proprietary Super
β eta 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 con-
vert 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.
The MIC3975 is fully protected with overcurrent limiting,
thermal shutdown, and reversed-battery protection. Fixed
voltages of 5.0V, 3.3V, 3.0, 2.5V, 1.8V, and 1.65V are avail-
able. An adjustable output voltage option is available for
voltages down to 1.24V.
For other voltages, contact Micrel.
