LT1120 Micropower Regulator with Comparator and Shutdown U U FEATURES ■ 40μA Supply Current ■ 125mA Output Current ■ 2.5V Reference Voltage ■ Reference Output Sources 2mA and Sinks 2mA ■ Open Collector Comparator Sinks 10mA ■ Logic Shutdown ■ 0.2V Dropout Voltage ■ Thermal Limiting ■ Available in 8-Lead DIP and SO Packages U APPLICATIO S ■ Battery Systems ■ Battery-Backup System ■ Portable Terminals ■ Portable Instruments ■ Memory Keep-Alive DESCRIPTIO The LT®1120 is a combination micropower positive regulator 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.
