et4U.coGeneral Description
eThe IL1117 is a series of low dropout voltage regulators which can provide
hup 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
Sadjustable version. On chip precision trimming adjusts the reference/
output voltage to within ± 2%. Current limit is also trimmed to ensure
taspecified output current and controlled short-circuit current.
The IL1117 series is available in SOT-223 packages.
aA minimum of 10uF tantalum capacitor is required at the output to
improve the transient response and stability.

NOTES: (1) IL1117-x adjustable versions require a minimum load current for ±3% regulation.
(2) Dropout voltage is the input voltage minus output voltage that produces a 1% decrease in output voltage.
