LR1116/A
LOW DROP FIXED AND
ADJUSTABLE POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC
LR1116/A
is a low drop voltage regulator able to
provide up to 0.8/1.0A 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.
