REG1118

800mA Low Dropout Positive Regulator

with Current Source and Sink Capability

DESCRIPTION

FEATURES

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.

● SOURCES 800mA, SINKS 400mA

● 2.85V OUTPUT FOR SCSI ACTIVE

NEGATION TERMINATION

● 1.3V max DROPOUT VOLTAGE AT

I_O= 800mA

● INTERNAL CURRENT LIMIT

● THERMAL OVERLOAD PROTECTION

● SOT-223 SURFACE MOUNT PACKAGE

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.

APPLICATIONS

● SCSI-2 AND SCSI-3 DEVICES

● FAST-20 SCSI

REG1118 is packaged in a SOT-223 surface-mount

package, suitable for reflow soldering techniques.

● ACTIVE NEGATION SCSI TERMINATORS

● SUPPLY SPLITTER GROUND GENERATION
