9.2.1.1 Design Requirements

The device component count is very minimal. No external components are usually required. However, TI recommends input or output capacitors depending on the distance between the device and the power supply and if extra filtering is needed at the output.

The output voltage is set based on the selection of the two resistors (R1 and R2), as shown in Figure 14.
