Output Trim Equations
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.
Vo_req=Desired (trimmed) output voltage [V]
Vo=1.503 V for 1.5 V output; Vo=1.804 V for 1.8 V output; Vo=2.505 V for 2.5 V output; Vo=3.308 V for 3.3 V
output; Vo=5.002 V for 5 V output; Vo=12.007 V for 12 V output.
