OPERATIONAL EXPLANATION (Continued)
< Output Voltage Setting>
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based
on the values of R

and R

< The use of ceramic capacitor CL >
The circuit of the XC9103/04/05 series is organized by a specialized circuit, which reenacts negative feedback of both
voltage and current. Also by insertion of approximately 100m
a high degree of stability is possible even using a ceramic capacitor, a condition which used to be difficult to achieve.
Compared to a tantalum condenser, because the series can be operated in a very small capacity, it is suited to use of the
ceramic capacitor, which is cheap and small.

XP161A1355PR (N-ch Power MOSFET, TOREX)
Note*: As the breakdown voltage of XP161A1355 is 8V, take care
with the power supply voltage.
With output voltages over 6V, use the XP161A1265 with a
breakdown voltage of 12V.
