The REG1118-2.85 is a three-terminal voltage regula- tors 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. Laser trimming assures excellent output voltage accu- racy. An NPN output stage allows output stage drive current to contribute to the source load current for maximum efficiency. REG1118 is packaged in a SOT-223 surface-mount package, suitable for reflow soldering techniques.
