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.
8.1 Application Information
The TPS7A6650H-Q1 device is a 150-mA low-dropout linear regulator designed for up to 40-V Vin operation with
only 12-µA quiescent current at no load.
8.2 Typical Application
Figure 16 shows a typical application circuits for the TPS7A6650H-Q1. 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 X7R or X8R.
