This is accomplished by connecting resistor Rv between the +Vout and +Sense pins and a resistor Rtrim of value 6.8kΩ between the trim and -Sense pins. See longform datasheet for connection diagram. The trim pin should be left open if trimming is not being used. The trim resistor can be determined by the following equations: 1.24 x Vf = 7.68 + 6.8 x 33 6.8 + 33 6.8 x 33 6.8+ 33 Vtrim = (Vo + R v) x Vf R v : Variable Resistor, KΩ Rtrim: KΩ, 6.8 kΩ recommended Vo: Nominal Output Voltage Vtrim: Desired Output Voltage Thermal Resistance Information Derating Curve Maximum Power Dissipation vs Ambient Temperature and Air Flow without heatsink 90 Natural Convection 20 ft./min.
