ADJ/GND 2. Output 3. Input TO-263 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. .DApplications w● Post Regulator for switching DC/DC Converter ● High Efficiency Linear Regulator w● Battery Chargers ● PC Add on Card w● Motherboard clock supplies ● LCD Monitor m● Set-top Box U.coAbsolute Maximum Ratings et4● Maximum Input Voltage ~ 15.0V e● Operating Junction Temperature Range -25℃ ~ 125℃ www.DataSh●Storage Temperature Range -50℃ ~ 150℃ 1 IL1117-xx Electrical Characteristics (Vin = 5V, Co = 10uF, Ta = 25℃, unless otherwise specified) PARAMETER OUTPUT VOLTAGE IL1117-1.2 IL1117-1.25 (Adjustable) IL1117-1.5 IL1117-1.8 IL1117-2.5 IL1117-2.85 IL1117-3.3 IL1117-5.0 CONDITIONS Tj = -25°C to +125°C Io = 10mA to 1.0A, Vin = 2.7 to 12.0V Io = 10mA to 1.0A, Vin = 2.8 to 12.0V Io = 10mA to 1.0A, Vin = 3.0 to 12.0V Io = 10mA to 1.0A, Vin = 3.3 to 12.0V Io = 10mA to 1.0A, Vin = 4.0 to 12.0V Io = 10mA to 1.0A, Vin = 4.4 to 12.0V Io = 10mA to 1.0A, Vin = 4.8 to 12.0V Io = 10mA to 1.0A, Vin = 6.5 to 15.0V MIN TYP MAX UNIT 1.176 1.225 1.470 1.764 2.450 2.790 3.240 4.900 1.200 1.250 1.500 1.800 2.500 2.850 3.300 5.000 1.224 1.280 1.530 1.836 2.550 2.910 3.360 5.100 V LINE REGULATION IL1117-1.2 IL1117-1.25 (Adjustable) IL1117-1.5 IL1117-1.8 IL1117-2.5 IL1117-2.85 IL1117-3.3 IL1117-5.0 Io =10mA to 1.0A, Vin = 2.7 to 12.0V Io =10mA to 1.0A, Vin = 2.8 to 12.0V Io =10mA to 1.0A, Vin = 3.0 to 12.0V Io =10mA to 1.0A, Vin = 3.3 to 12.0V Io =10mA to 1.0A, Vin = 4.0 to 12.0V Io =10mA to 1.0A, Vin = 4.4 to 12.0V Io =10mA to 1.0A, Vin = 4.8 to 12.0V Io =10mA to 1.0A, Vin = 6.5 to 15.0V 0.1 0.2 % 2.0 7.0 mV 2.0 7.0 mV 2.0 7.0 mV 2.0 7.0 mV 2.0 7.0 mV 3.0 7.0 mV 4.0 10.0 mV LOAD REGULATION IL1117-1.2 IL1117-1.25 (Adjustable) IL1117-1.5 IL1117-1.8 IL1117-2.5 IL1117-2.85 IL1117-3.3 IL1117-5.0 Io = 10mA to 1.0A, Vin = 3.2V Io = 10mA to 1.0A, Vin = 3.3V Io = 10mA to 1.0A, Vin = 3.5V Io = 10mA to 1.0A, Vin = 3.8V Io = 10mA to 1.0A, Vin = 4.5V Io = 10mA to 1.0A, Vin = 4.85V Io = 10mA to 1.0A, Vin = 5.3V Io = 10mA to 1.0A, Vin = 7.0V 0.2 0.4 % 3.0 10.0 mV 3.0 10.0 mV 3.0 10.0 mV 3.0 10.0 mV 3.0 10.0 mV 4.0 12.0 mV 5.0 15.0 mV DROPOUT VOLTAGE (2) All Models CURRENT LIMIT MINIMUM LOAD CURRENT Adjustable Models Io = 800mA Io =1A Io =1A (Tj = -25°C to +125°C.)
