LT1120AIS8#PBF

LT1120A is a combination micropower positive regulator and free collector comparator on a single monolithic chip. 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. The comparator can be used for system or battery monitoring. 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. It is widely used in application such as battery systems, battery backup system, portable terminals, portable instruments, memory keep alive etc.
