IL1117C-xxLow Dropout Positive Voltage Regulator TECHNICAL DATA
Description
The IL1117C is a series of low dropout voltage
regulators which can provide up to 1A of output cur-
rent. The IL1117C 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 IL1117C 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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those indi-
cated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
