CS8182
Micropower 200 mA
Low Dropout Tracking
Regulator/Line Driver
The CS8182 is a monolithic integrated low dropout tracking
regulator designed to provides an adjustable buffered output voltage
that closely tracks (±10 mV) the reference input. The output delivers
up to 200 mA while being able to be configured higher, lower or equal
to the reference voltages.
The device has been designed to operate over a wide range (2.8 V to
45 V) while still maintaining excellent DC characteristics. The
CS8182 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
REF
/ENABLE lead serves two purposes. It is used to provide
the input voltage as a reference for the output and it also can be pulled
low to place the device in sleep mode where it nominally draws less
than 30
mA
from the supply.
