APPLICATION NOTES
1. OUTPUT TRIMMING
The output voltages are preset to nominal values as indicated by the models table at the factory. If desired, the output voltage may
optionally be trimmed to a different value (+/- 10%) with external resistors and/or potentiometer as shown below.
To trim the output voltage with fixed resistors, the output voltage can be calculated as follows.
