General Description

The IL1117 is a series of low dropout voltage regulators which can provide

up to 1A of output current. The IL1117 is available in seven fixed voltage,

1.2, 1.25, 1.5, 1.8, 2.5, 2.85, 3.3 and 5.0V. Additionally it is also available 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.

The IL1117 series is available in SOT-223 packages.

A minimum of 10uF tantalum capacitor is required at the output to

improve the transient response and stability.
