Product Summary

The MIC39100-2.5BS is a 1A lowdropout linear voltage regulator that provides low-voltage, high-current output from an extremely small package. Utilizing Micrel proprietary Super βeta PNP pass element, the MIC39100-2.5BS offers extremely low dropout (typically 410mV at 1A) and low ground current (typically 11mA at 1A). The MIC39100-2.5BS is a fixed output regulator offered in the SOT-223 package. The MIC39100-2.5BS is a fixed and adjustable regulator, respectively, in a thermally enhanced power 8-lead SOP (small outline package). The MIC39100-2.5BS 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 MIC39100-2.5BS to provide 2.5V from a supply as low as 3.13V and 1.8V from a supply as low as 2.43V. The applications of the MIC39100-2.5BS are: LDO linear regulator for PC add-in cards; PowerPCpower supplies; High-efficiency linear power supplies; SMPS post regulator; Multimedia and PC processor supplies; Battery chargers; Low-voltage microcontrollers and digital logic.
