Trim

This feature allows increasing and decreasing the output voltage of single output models. This is accomplished by

connecting an external resistor between the Trim pin an either the +Vout or -Vout pin. The resulting external Trim resistor

is speciﬁed in Ohm and needs to be at least 1/16 Watt of rated power.
