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.
Minimum trim down voltage is 2.97V
Maximum trim up voltage is 3.63V.
The total voltage increased by trim and remote sense should not exceed 10% of the nominal output voltage.
Note:
Vo_req=Desired (trimmed) output voltage [V]
Output voltage Vo=3.308 V
