The CS8182 is a monolithic integrated low dropout tracking regulator designed to provide 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 output 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 VREF/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 30μA from the supply.
