This document describes the characteristics, operation, and use of the TPS71401DRVEVM-426
evaluation module (EVM). This EVM demonstrates the capabilities and features of Texas Instruments'

TPS71401

a low-dropout (LDO) linear regulator, an 80-mA, low quiescent current linear regulator in a

2-mm x 2-mm SON package. The TPS71401DRVEVM-426 EVM helps designers evaluate the operation
and performance of the TPS71401 LDO in a variety of configurations.
