Output Voltage Adjust (see operating information)
Passive adjust
The resistor value for an adjusted output voltage is calculated by
using the following equations:
Output Voltage Adjust Upwards, Increase:
Example: Increase 4% =>V
Output Voltage Adjust Downwards, Decrease:
Example: Decrease 2% =>V

Active adjust
The output voltage may be adjusted using a voltage applied to the
Vadj pin. This voltage is calculated by using the following equation:
Example: Upwards => 12.5 V
Example: Downwards => 11.0 V
