TPS7A53EVM-080 Evaluation Module

ABSTRACT

TPS7A53EVM-080 Evaluation Module

This user's guide describes the operational use of the TPS7A53EVM-080 evaluation module (EVM) as 
a reference design for engineering demonstration and evaluation of the TPS7A53A-Q1 low-dropout linear 
regulator (LDO). Included in this user's guide are setup and operating instructions, thermal and layout guidelines, 
a printed circuit board (PCB) layout, a schematic diagram, and a bill of materials (BOM).

Throughout this document, the terms 

evaluation board

evaluation module

, and 

EVM

 are synonymous with the 

TPS7A53EVM-080.
