The REG1118-2.85 is a three-terminal voltage regulators capable of sourcing up to 800mA and sinking up to 400mA. The sinking capability is important in SCSI applications where active negation line drivers are used. The REG1118-2.85 is useful for making a 27-line Boulay terminator capable of interfacing with active negation drivers required in FAST-20 SCSI applications. The regulator has active current limits for both sink and source currents as well as internal thermal limiting.
