GENERAL DESCRIPTION
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 (V
OUT
=5.0V) and
the XB1117P18 / 25 / 30 (V
OUT
=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 (10F, tantalum) and an output
capacitor. Package is available in SOT-223.
