I
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 2% =>Vout = 12.24 Vdc
Output Voltage Adjust Downwards, Decrease:
Example: Decrease 4% =>V

Active adjust
The output voltage may be adjusted using a {current/voltage} applied to the
Vadj pin. This {current/voltage} is calculated by using the following equations:
Example: Upwards => 12.50 V
Example: Downwards => 12.50 V
