L1117XG Series

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

z 5V to 2.5V or 3.3V linear regulators

z Low voltage micro-controllers

z Battery Chargers

The L1117G Series regulators offer fixed and

adjustable voltage options available in the

popular industry standard SOT-223, TO-220,

TO-252 and TO-263 packages.

* 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.
