9.3.5 Adjustable Output Voltage (ADJ for TPS7B6701)

An output voltage between 1.5 V and 18 V can be selected by using the external resistor dividers. Use Equation 2 to calculate the output voltage, where VADJ = 1.233 V. In order to avoid a large leakage current and to prevent a divider error, the value of (R1 + R2) must between 10 k and 100 kΩ.
