40µA Supply Current  
The LT1020 is a combination micropower positive regula-  
tor and free collector comparator on a single monolithic  
chip. With only 40µA supply current, the LT1020 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 dropout detector  
provides an output current to indicate when the regulator  
is about to drop out of regulation.

The dual output comparator can be used as a comparator  
for system or battery monitoring. For example, the com-  
parator can be used to warn of low system voltage while  
the dropout detector shuts down the system to prevent  
abnormaloperation.Frequencycompensationofthecom-  
parator for amplifier applications can be obtained by  
adding external output capacitance. Dual output or posi-  
tive and negative regulators can also be made.

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