■GENERAL DESCRIPTION

■FEATURES

The XB1117 series is a 1A low dropout positive 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

the XB1117P18 / 25 / 30 (VOUT=1.8V, 2.5V and 3.0V) and

XB1117K type. 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 (10μF, tantalum) and an output

capacitor. Package is available in SOT-223.
