( Vo , nom Vo , adj)
Where Radj-down is the resistance value and G, H, and L are defined in Table 7.
With an external resistor between the Vadj Pin and -Vout Pin (Radj-up) the output voltage set point
(Vo,adj) increases (see Figure 15). The following equation determines the required external
resistor value to obtain an adjusted output voltage:
