• Typical Application Circuit for LT1120AIS8 5V Micropower Regulator. The LT1120A is a combination micropower positive regulator and free collector comparator on a single monolithic chip. With only 20 uA supply current, the LT1120A can supply over 125mA of output current. Input voltage range is from 4.5V to 36V and dropout voltage is 0.6V at 125mA. Dropout voltage decreases with lower load currents. Also included on the chip is a class B output 2.5V reference that can either source or sink current. This allows it to be used as a supply splitter or auxiliary output. A shutdown pin allows logic shutdown of the output
