General Description
LT1120CN8_1055362 General Description
The LT®1120 is a combination micropower positive regu- lator and free collector comparator on a single monolithic chip. With only 40µA supply current, the LT1120 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. A shutdown pin allows logic shutdown of the output.
The comparator can be used for system or battery moni-toring. For example, the comparator can be used to warn of low system voltage. Frequency compensation of the comparator for amplifier applications can be obtained by adding external output capacitance.
The 2.5V reference will source or sink current. This allows it to be used as a supply splitter or auxiliary output.
