PRODUCTION DATA
Figure 7-1 shows the typical application circuit for the TPS748 adjustable output device.
R1 and R2 can be calculated for any output voltage using the formula shown in Figure 7-1. Table 7-1 lists sample resistor values of common output voltages. In order to achieve the maximum accuracy specifications, R2 must be ≤ 4.99 kΩ.
