6.3.2 Traditional Adjustable Configuration

For any output voltage target that is not supported in the User-Configurable Output VoltageUser-Configurable Output Voltage section, a traditional adjustable configuration with external-feedback resistors can be used with the TPS7A7300. Figure 6-7 shows how to configure the TPS7A7300 as an adjustable regulator with an equation and Table 6-2 lists recommended pairs of feedback resistor values.

Note:

The bottom side of feedback resistor R2 in Figure 6-7 must be in the range of 27 kΩ to 33 kΩ to maintain the specified regulation accuracy.
