1.0A Low Dropout Positive Voltage Regulator

The IL1117 is a series of low dropout voltage regulators 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 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, TO-252, TO-220 packages.

A minimum of 10uF tantalum capacitor is required at the output to improve the transient response and stability.
