Output Trim Equations
Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected
between the Trim pin and GND pin. The Trim Up resistor should be connected between the Trim pin and the Vout
pin. Only one of the resistors should be used for any given application.
Note:
Vo_req=Desired (trimmed) output voltage [V]
Output voltage Vo=3.308 V
