7.2.2.1 ANY-OUT Programmable Output Voltage

For ANY-OUT operation, the TPS7A7300 does not use any external resistors to set the output voltage, but uses device pins labeled 50 mV, 100 mV, 200 mV, 400 mV, 800 mV, and 1.6 V to set the regulated output voltage. Each pin is either connected to ground (active) or is left open (floating). The ANY-OUT programming is set as the sum of the internal reference voltage (V(SS) = 0.5 V) plus the sum of the respective voltages assigned to each active pin. By leaving all ANY-OUT pins open, or floating, the output is set to the minimum possible output voltage equal to V(SS). By grounding all of the ANY-OUT pins, the output is set to 3.65 V.

When using the ANY-OUT pins, the SNS pin must always be connected between the OUT and FB pins. However, the feedforward capacitor must be connected to the FB pin, not the SNS pin.
