General Description

The MIC37100, MIC37101, and MIC37102 are 1A 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 MIC37100/01/02 offers extremely low dropout (typically 280mV at 1A) and low ground current (typically 11mA at 1A).
