8.1 Application Information
R1 and R2 can be calculated for any output voltage using the formula in Figure 8-4. Table 8-1 lists sample resistor values of common output voltages. To achieve the maximum accuracy specifications, R2 must be less than or equal to 4.99 k?. Table 8-2 lists the capacitor values for setting the soft-start time.
Table 8-1 Standard 1% Resistor Values
for Programming the Output Voltage(1)
| R1 (k?) | R2 (k?) | VOUT (V) |
|---|---|---|
| Short | Open | 0.8 |
| 0.619 | 4.99 | 0.9 |
| 1.13 | 4.53 | 1 |
| 1.37 | 4.42 | 1.05 |

| 3.57 | 1.15 | 3.3 |
(1) VOUT = 0.8 × (1 + R1 / R2).
