Note: 7. The sense pins can be used to compensate for any voltage drops (per indicated max limits) that may
occur along the connection between the output pins to the load. Pin 8 (+Sense) and Pin 6 (-Sense) should
be connected to Pin 9 (+Vout) and Pin 5 (Return) respectively at the point where regulation is desired.
8. Refer to Equation (1) and (2) and Figures 3 and 4 for the Output Trim Adjust configuration.
9. The combination of remote sense and Trim adjust cannot exceed 110% of VO, NOM
