TPS75005EVM-023  
This users guide describes the characteristics, operation, and use of the TPS75005EVM-023 evaluation  
module (EVM). The TPS75005EVM-023 is a reference design for engineering demonstration and  
evaluation of the TPS75005 dual low-dropout linear regulator (LDO) and triple voltage rail monitor from  
Texas Instruments. This users guide includes setup and configuration instructions, a complete schematic  
diagram, bill of materials (BOM), and printed circuit board (PCB) layouts for the evaluation module.  
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with  
the TPS75005EVM-023 unless otherwise noted.
