1A Fixed and Adjustable Low
Dropout Linear Regulator (LDO)
L1117 Series
SOT-223, TO-252,
TO-220,TO-263
GENERAL DESCRIPTION
The L1117 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.
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.
The L1117 Series regulators offer fixed and
adjustable voltage options available in the
popular industry standard SOT-223, TO-220,
TO-252 and TO-263 packages.
FEATURES
z Fixed 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

* 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.
