Product Summary

The MIC39300-2.5BU TR is a 3.0A low-dropout linear voltage regulators that provide a low voltage, high-current output with a minimum of external components. Utilizing Micrels proprietary Super beta PNP pass element, the MIC39300-2.5BU TR offers extremely low dropout (typically 400mV at 3.0A) and low ground current (typically 36mA at 3.0A). Applications are (1)LDO linear regulator for PC add-in cards; (2)High-efficiency linear power supplies; (3)SMPS post regulator; (4)Multimedia and PC processor supplies; (5)Low-voltage microcontrollers; (6)StrongARM processor supply.
