9.2.1.2.2 Output Voltage Configuration

The output voltage is configured using Equation 1. Therefore, RSET = VSS_SET / ISET = 1.8 V / 100 μA = 18 kΩ. An 18 kΩ 0.1% tolerance resistor is selected. Using a 1% tolerance resistor is also acceptable, but this could contribute 1% error directly to the output voltage. Similarly, a 12 kΩ 0.1% tolerance resistor is selected for RREF.
