Note
1. The follow output voltage can be outputted by connecting this terminal to an output + or – terminal. Unless the output voltage is adjusted, this terminal
should be open.
2. In addition, the voltage can be adjusted not by shorting these terminals, but by connecting them to resistances as shown below.
3. Arithmetic expression connected resistance: R ( K )
3-1 Vo=(3.3*R+36.7)/(R+10) 3-2 Vo=(3.3*R+36.7)/(R+12.92)
3-3 Vo=2.5*[2+2.7/(R+6.8)] 3-4 Vo=2.5*[2-2.7/(R+9.5)]
3-5 Vo=2.5+9.5(R+10.9)/(R+8.2) 3-6 Vo=2.5+22*(R+12.7)/(R+10)(Between two outputs)

5. The filter capacitor recommended use “ CHEMICON “ KMF series
or equivalent impedance at 0.16 ~ 0.33 ( 100KHz 20 )
6. Maximum value at nominal input voltage and full load.
7. Typical value at nominal input voltage and full load.
