9.2.2.4 Setting Output Voltage

The output voltage is set by an external resistor divider (R1, R2 in the Functional Block Diagram). Typically, a minimum current of 20 μA flowing through the feedback divider gives good accuracy and noise covering. A standard 56-kΩ resistor is typically selected for low-side resister R2.

The value of R1 is then calculated as:
