TPS782xxEVM
This user’s guide describes the characteristics, operation, and use of the TPS782xxEVM-445 where ‘xx’ is
the output voltage. This EVM demonstrates the Texas Instruments TPS782xx, a low dropout linear
regulator in a TSOT23-5 package that is capable of 150 mA of output current. This user’s guide includes
setup instructions, a schematic diagram, thermal guidelines, a bill of materials, and printed-circuit board
layout drawings for the evaluation module.

TPS782xxEVM-445 Bill of Materials
The TPS782xxEVM-445 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS78225, TPS78227, TPS78230, and the TPS78233 low dropout linear regulators in
the TSOT23-5 package. The TPS782xx is a 150-mA, ultralow, quiescent-current linear regulator.
