SOT-223, TO-252,
TO-220,TO-263
1A Fixed and Adjustable Low
Dropout Linear Regulator (LDO)
NIKO-SEM
Lead-Free
GENERAL DESCRIPTION
FEATURES
The L1117G Series are positive and low
drop- out three-terminal voltage regulators
with 1A output current capability. These
devices are designed for use in low voltage
applica- tions that offers lower dropout
voltage and faster transient response.
z Fixed 1.8V, 2.5V, 2.85V, 3.3V, 5V or
adjustable output voltage
z Low dropout voltage:
1.2V typical at up to 1A
z Low ground current
z Fast transient response
z Current & thermal limiting
z Line regulation: 0.5% typical
z Load regulation: 0.5% typical

package
These devices are fully protected against
over current faults, over temperature oper-
ation, reversed input polarity, reversed lead
insertion, transient voltage spike …etc.
On-Chips trimming the reference voltage to
2% and features the low dropout of maxi-
mum 1.45 volts.
APPLICATIONS
z 2.85V active SCSI terminators
z 7-15V to 5V linear regulators

* When considering short circuits to ground, the maximum input-to-output differential voltage shall not be allowed
greater than approximate 2~3V at values of supply voltage in excess of 10V, continuous short-circuits can exceed
the power dissipation ratings and cause eventual destruction.
