TPS727xxYFF EVM
This User’s Guide describes the characteristics, operation, and use of the TPS727xxYFFEVM-407. This
EVM demonstrates the Texas Instruments TPS727xx, a Low Drop Out (LDO) linear regulator in a chip
scale (WCSP-4) package that is capable of 200mA of output current. This user’s guide includes setup
instructions, a schematic diagram, thermal guidelines, a bill of materials (BOM), and PCB layout drawings
for the evaluation module.

1 Introduction
The TPS727xxYFFEVM-407 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS727xx LDO in the WCSP-4 package. The TPS727xx is a 200mA, ultra-low Iq, fast
transient response, linear regulator.
