The output voltage of the TPSM8281x is adjustable. Choose resistors R1 and R2 to set the output voltage within a range of 0.6V to 5.5V according to Equation 10. To keep the feedback (FB) net robust from noise, set R2 equal to or lower than 100kΩ to have at least 6µA of current in the voltage divider. Lower values of FB resistors achieve better noise immunity, and lower light load efficiency, as explained in the Design Considerations for a Resistive Feedback Divider in a DC/DC Converter analog design journal.
