UTC LR1116/A LINEAR INTEGRATED CIRCUIT
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 (Vref=1.25V). Output consists of
pnp power transistor. So that dropout voltage can be
extremely low.
