Product Information

1.0A Low Dropout Positive Voltage Regulator IL1117-xx et Features 4U . om c TECHNICAL DATA w w ● Adjustable and Fixed of 1.2, 1.25, 1.5, 1.8, 2.5, 2.85, 3.3, 5.0V ● Space saving SMD types of SOT-223 ● 1.2V Drop-out Voltage ● 1.0A Output Current ● Line Regulation Typically at 0.2% max ● Current Limiting and Thermal Protection w .D ta a he S SOT-223 TO-220 TO-252 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.
