The TPS7A84 can use either external resistors or the internally-matched ANY-OUT feedback resistor network to set output voltage. The ANY-OUT resistors are accessible via pin 2 and pins 5 to 11 and are used to program the regulated output voltage. Each pin is can be connected to ground (active) or left open (floating), or connected to SNS. ANY-OUT programming is set by Equation 4 as the sum of the internal reference voltage (V_NR/SS = 0.8 V) plus the accumulated sum of the respective voltages assigned to each active pin; that is, 50mV (pin 5), 100mV (pin 6), 200mV (pin 7), 400mV (pin 9), 800mV (pin 10), or 1.6V (pin 11). Table 8-2 summarizes these voltage values associated with each active pin setting for reference. By leaving all program pins open or floating, the output is thereby programmed to the minimum possible output voltage equal to V_FB.

Table 8-3 provides a full list of target output voltages and corresponding pin settings when the ANY-OUT pins are only tied to ground or left floating. The voltage setting pins have a binary weight; therefore, the output voltage can be programmed to any value from 0.8 V to 3.95 V in 50-mV steps when tying these pins to ground. There are several alternative ways to set the output voltage. The program pins can be driven using external general-purpose input/output pins (GPIOs), manually connected using 0-Ω resistors (or left open), or hardwired by the given layout of the printed circuit board (PCB) to set the ANY-OUT voltage. As with the adjustable operation, the output voltage is set according to Equation 5 except that R₁ and R₂ are internally integrated and matched for higher accuracy. Tying any of the ANY-OUT pins to SNS can increase the resolution of the internal feedback network by lowering the value of R₁. See the Section 8.1.10 section for additional information.
