LR1116/B
LOW DROP POSITIVE
VOLTAGE REGULATORS
DESCRIPTION
The UTC
LR1116/B
is a low drop voltage regulator able to provide
up to 0.8/0.5A of output current. Output consists of pnp power
transistor. So that dropout voltage can be extremely low.
LINEAR INTEGRATED CIRCUIT
FEATURES
* 2.85V device are suitable for SCSI-2 active termination
* Output current up to 0.8/0.5A
* Internal current and thermal limit
* Available in
±1%(at
25°C) and 2% in all temperature range
*Pb-free plating product number:
- LR1116L-xx
- LR1116BL-xx
