LM1117 1.0A Low Dropout Positive Voltage Regulator DESCRIPTION PIN CONFIGURATION The LM1117 is a series of low dropout voltage regulators wh- TO-220 ich can provide up to 1A of output current. The LM1117 is av- ailable in four fixed voltage, 1.2V,1.8V, 3.3V and 5.0V. Additi- onally it is also available in adjustable version. On chip preci- sion 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 LM1117 series is available in SOT-223 and TO-220 packages. A minimum of 10μF tantalum capacitor is required at the output to improve the transient response and stability.
