LINEAR INTEGRATED CIRCUIT
LOW DROP POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC LR1118 is a low drop voltage regulator able to provide
up to 1A of output current, available also for adjustable version
(VREF=1.24V). Output consists of PNP power transistor. So that
dropout voltage can be extremely low.
FEATURES
* 2.85V device are suitable for SCSI-2 active termination
* Output current up to 1A
* Adjustable version available.(VREF=1.24V)
* Internal current and thermal limit
*Pb-free plating product number: LR1118L
* Available in ±1%(at 25°C) and 2% in all temperature range

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied
2. The device is guaranteed to meet performance specifications within 0°C~+70°C operation temperature
range, and is assured by design from 0°C~+125°C.
