FEATURES

DESCRIPTION

The LT^®1118 family of low dropout regulators has the

unique capability of maintaining output regulation while

sourcingorsinkingloadcurrent. The2.85Voutputvoltage

regulator is ideal for use as a Boulay termination of up to

27 SCSI data lines. The regulator maintains regulation

while both sourcing and sinking current, enabling the use

of active negation drivers for improved noise immunity on

the data lines. Regulation of output voltage is maintained

for TERMPWR voltages as low as 4.0V. When unloaded,

quiescentsupplycurrentis alow600µA,allowingcontinu-

ous connection to the TERMPWR lines. An ultralowpower

shutdown mode is also available on the SO-8 version. In

Shutdown the output is high impedance and supply cur-

rent drops to less than 10µA.

■

Current limits in both sourcing and sinking modes, plus

on-chip thermal shutdown make the circuit tolerant of

output fault conditions.
