10 Application and Implementation
TLE4275-Q1
SLVS647I – AUGUST 2006 – REVISED NOVEMBER 2014
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.
10.1 Application Information
Figure 19 shows typical application circuits for the TLE4275-Q1. 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 in
order 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.
