200 mA LDO Linear Voltage Tracking Regulator with Enable

The CS8183 is a dual low dropout tracking regulator designed to provide adjustable buffered output voltages that closely track (110mV) the reference inputs. The outputs deliver up to 200mA 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 (2.8V to 45V) while still maintaining excellent DC characteristics.

The CS8183 is protected from reverse battery, short circuit and thermal runaway conditions. The device also can withstand 45V load dump transients and -50V reverse polarity input voltage transients. This makes it suitable for use in automotive environments.

The VREF/ENABLE leads serve two purposes. They are used to 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 30µA from the supply.
