XB1117 Series

1.0A Positive Voltage Regulator

The XB1117 series is 1A Bi-polar transistor LDO voltage regulator. Output voltage of the XB1117P series is fixed to 1.8V, 2.5V, 3.3V, and 5.0V. The XB1117K series output voltage is adjustable by the external resistors. Please refer to the absolute,maximum ratings for the difference between the rated input voltage of the XB1117P50 (VOUT=5.0V) and XB1117P18, 25, 31, K12B. With the dropout voltage 1.2V (TYP.), output current can be generated up to 1A. The built-in overcurrent circuit and,thermal protection circuit start to operate when either one of output put current reaches the current limit level or junction,temperature reaches the temperature limit. The XB1117 series provide stable line and load regulation by using an input,capacitor and an output capacitor (10μF, tantalum). Package is available in SOT-223.
