The MIC39102 are 1A lowdropout 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 MIC39102 offers extremely low dropout (typically 410mV at 1A) and low ground current (typically 11mA at 1A). The MIC39102 is fixed and adjustable regulators, respectively, in a thermally enhanced power 8-lead SOIC package. The MIC39102 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 630mV over all operating conditions allows the MIC39102 to provide 2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The MIC39102 is fully protected with overcurrent limiting, thermal-shutdown, and reverse-battery protection. Adjustable output voltages to 1.24V on MIC39102.
