Micropower Regulator with  
Comparator and Shutdown  
U
FEATURES  
DESCRIPTIO  
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.

Available in 8-Lead DIP, SO and Metal Can Packages  
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.

Battery-Backup System  
The 2.5V reference will source or sink current. This allows  
it to be used as a supply splitter or auxiliary output.
