LT1120
Micropower Regulator with
Comparator and Shutdown
The LT
1120 is a combination micropower positive regu-
lator and free collector comparator on a single monolithic
chip. With only 40
μ
A 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.
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.
The 2.5V reference will source or sink current. This allows
it to be used as a supply splitter or auxiliary output.
