TECHNICAL DATA

IL1117-xx

1.0A Low Dropout Positive Voltage Regulator

The IL1117 is a series of low dropout voltage regu-

SOT-223

TO-252

lators which can provide up to 1A of output current. The

IL1117 is available in eight fixed voltage, 1.2, 1.25, 1.5,

1.8, 2.5, 2.85, 3.3 and 5.0V. Additionally it is also avail-

able in adjustable version. On chip precision trimming

adjusts the reference/ output voltage to within

± 2%. Current limit is also trimmed to ensure specified

output current and controlled short-circuit current.

Pin#2 connected with heat

The IL1117 series is available in SOT-223, TO-

252, TO-220 packages.

sink

IL1117-xxD0T

A minimum of 10uF tantalum capacitor is required

at the output to improve the transient response and sta-

bility.
