8.2 Typical Applications

Figure 24 and Figure 26 depict typical application circuits for the TPS7A66-Q1 and TPS7A69-Q1, respectively. One may use different values of external components, depending on the end application. An application may require a larger output capacitor during fast load steps in order to prevent reset from occurring. TI recommends a low-ESR ceramic capacitor with dielectric of type X5R or X7R.
