XB1117
XB1117 Series
1A Low Dropout Positive Voltage Regulator
ETR0315_005a
GENERAL DESCRIPTION
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 (10 F, tantalum). Package is available in SOT-223.
