8.2.1.1 Adjustable Output Voltage (Feedback Circuit)

The output voltage of the TPS7H1101A-SP can be set to a user-programmable level between 0.8 V and 6.65 V. Achieve this by using a resistor divider connected between VOUT, FB, and GND terminals. RTOP connected between VOUT and VFB, and RBOTTOM connected between VFB and GND.

Use Equation 2 to determine VOUT.
