Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and Sense (-) pin. The Trim Up resistor should be connected between the Trim pin and the
Sense (+). Only one of the resistors should be used for any given application.
Note:
Vo_req=Desired (trimmed) output voltage [V]
Output voltage Vo=3.305 V
