LR1116/A/B

LINEAR INTEGRATED CIRCUIT

LOW DROP FIXED AND

ADJUSTABLE POSITIVE

VOLTAGE REGULATORS

SOT-223

SOP-8

ꢀ

DESCRIPTION

The UTC LR1116/A/B is a low drop voltage regulator able to

TO-220

TO-252

provide up to 0.8/1.0/0.5A of output current, available also for

adjustable version (V_REF=1.25V). Output consists of pnp power

transistor. So that dropout voltage can be extremely low.
