7.2 Typical Application
Figure 7-1 shows a typical application circuit for the TPS7B63-Q1. Different values of external components can be used, depending on the end application. An application may require a larger output capacitor during fast load steps to prevent a large drop on the output voltage. TI recommends using a low-ESR ceramic capacitor with a dielectric of type X7R.
