Design Requirements

R1 and R2 can be calculated for any output voltage using the formula shown in Figure 7-2. Sample resistor values for common output voltages are shown in Figure 7-3. For best accuracy, make the parallel combination of R1 and R2 approximately 19 kΩ.

TPS732-Q1 Adjustable Voltage Version
VOUT = ( R1 + R2 ) / R2 × 1.204
R1 || R2 ≅ 19 kΩ for best accuracy.
