7.3 Feature Description

7.3.1 Adjusting the Output Voltage (VADJ)

The VADJ pin programs the output voltage of the TPSM84A21. The output voltage adjustment range is from

VOUT. TI recommends to make the VS+ connection at the load for the best load regulation performance. The

along with the actual output voltage and the set-point error when using the E96 resistor value. For the most

accurate output voltage set-point it is best to use the ideal resistor value. The ideal resistor value may not be a

standard value and may require two standard value resistors in series or parallel to obtain the desired output

voltage.
