VOLTAGE ADJUSTMENT
V

OUT
For large adjustment range use a 50 K potentiometer.
This method gives good results when a voltage lower
than the rated output is needed.

R1
For small changes in output voltage use R1 to increase
the output voltage or R2 to decrese the output voltage.
The graph at right shows the approximate resistance
values. The initial output voltage is indicated on the
graph. (3 V = TK11530 etc.)
