Microchip | MIC3775YMM

The MIC3775YMM is a 750 mA low-dropout linear voltage regulators that provides low-voltage, high-current output from an extremely small package. Utilizing Micrel’s proprietary Superbeta PNP™ pass element, the MIC3775 offers extremely low-dropout (typically 280 mV at 750 mA) and low ground current (typically 7.5 mA at 750 mA).

The MIC3775-2.5YMM is ideal for PC add-in cards that need to convert from standard 5 V to 3.3 V or 3.0 V, 3.3 V to 2.5 V or 2.5 V to 1.8 V or 1.65 V. A guaranteed maximum dropout voltage of 500 mV over all operating conditions allows the MIC3775 to provide 2.5 V from a supply as low as 3.0 V and 1.8 V or 1.5 V from a supply as low as 2.25 V.

The MIC3775 is fully protected with overcurrent limiting, thermal shutdown, and reversed-leakage protection. Fixed and adjustable output voltage options are available with an operating temperature range of –40°C to +125°C
