CS8183

Dual Micropower 200 mA
Low Dropout Tracking
Regulator/Line Driver

The CS8183 is a dual low dropout tracking regulator designed to

provide adjustable buffered output voltages that closely track
(±10 mV) the reference inputs. The outputs deliver up to 200 mA
while being able to be configured higher, lower or equal to the
reference voltages.

The outputs have been designed to operate over a wide range (2.8 V
to 45 V) while still maintaining excellent DC characteristics. The
CS8183 is protected from reverse battery, short circuit and thermal
runaway conditions. The device also can withstand 45 V load dump
transients and −50 V reverse polarity input voltage transients. This
makes it suitable for use in automotive environments.

The V
provide the input voltage as a reference for the output and they also
can be pulled low to place the device in sleep mode where it nominally
draws less than 30 µA from the supply.

The two trackers can be combined in parallel doubling the capability
to 400 mA for a single application.
