Output Voltage Trimming
It allows the user to increase or decrease the output voltage of the module. This is accomplished by connecting an external resistor between the Trim pin and
either the +Vout or -Vout pins. With an external resistor between the Trim and -Vout pin, the output voltage increases. With an external resistor between the
Trim and +Vout pin, the output voltage decreases. The external Trim resistor needs to be at least 1/16W of rated. The values for trim resistors shown in trim
tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
