LT1020

Micropower Regulator

and Comparator

FEATURES

DESCRIPTIO

The LT^®1020 is a combination micropower positive regu-

lator 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.
