Utilizing Micrel’s proprietary Superβeta PNP ® pass element, the MIC3775 offers extremely low-dropout (typically 280mV at 750mA) and low ground current (typically 7.5mA at 750mA). The MIC3775 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V or 3.0V, 3.3V to 2.5V or 2.5V to 1.8Vor 1.65V. A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC3775 to provide 2.5V from a supply as low as 3.0V and 1.8V or 1.5V from a supply as low as 2.25V. 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. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
