The LT1020 is a combination micropower positive regula-
tor and free collector comparator on a single monolithic
chip. With only 40
μ
A 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
abnormal operation. Frequency compensation of the com-
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.
