DESCRIPTION
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.
