NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
Based on the end-application, different values of external components can be used. An application can require a
larger output capacitor during fast load steps to prevent a reset from occurring. TI recommends a low-ESR
ceramic capacitor with a dielectric of type X5R or X7R for better load transient response.
9.2 Typical Application
Figure 14 shows typical application circuits for the TL720M05-Q1 device.
