Case*
*The case ground connection should be as low an impedance as possible to minimize EMI.
Direct contact of baseplate to chassis ground provides the lowest impedance.

Notes
If calculated result is a negative value, the desired output voltage is outside the allowed trim range.
Calculated values of RT are ±15%.
When trimming up, do not exceed the maximum output power.
When trimming down, do not exceed the maximum output current.
