Cap Low-Voltage Low-Dropout Regulator
Final
General Description
The MIC3775 is a 750mA low-dropout linear voltage regula-
tors that provides low-voltage, high-current output from an
extremely small package. Utilizing Micrel’s proprietary
Super
β
eta PNP pass element, the MIC3775 offers ex-
tremely 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 1.8V
or 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.
