Output Trim Equations

Trim Resistor Calculate

Equations for calculating the trim resistor are shown below (Unit: kΩ). The Trim Down resistor should be

connected between the Trim pin and Ground pin. The Trim Up resistor should be connected between the Trim

pin and the Vout. Only one of the resistors should be used for any given application.

1) For Vo=1.5 V – 12 V:

Vo=12.006 V for 12 V output; Vo=5.000 V for 5 V output; Vo=3.308 V for 3.3 V output; Vo=2.505 V for 2.5 V

output; Vo=1.804 V for 1.8 V output; Vo=1.503 V for 1.5 V output

2) For Vo=1.2 V:
