CS8182

Micropower 200 mA Low Dropout Tracking Regulator/Line Driver

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 V 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A from the supply.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously . If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
