1.0A Low Dropout Positive Voltage Regulator

IL1117-xxET

IL1117-xxD0T

The IL1117 is a series of low dropout voltage regu-

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.

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 sta-

bility.
