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.

IL1117-xxD0T
A minimum of 10uF tantalum capacitor is required
at the output to improve the transient response and sta-
bility.
