8 Application and Implementation
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, as well as validating and testing their design
implementation to confirm system functionality.
8.1 Application Information
The TPS799 LDO regulator provides high PSRR while maintaining ultra-low current consumption. The device
also features inrush current protection and overshoot detection at the output.
8.2 Typical Application
Figure 8-1 and Figure 8-2 show the basic circuit connections.
