LP592201EVM User Guide

The Texas Instruments LP592201EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the adjustable LP592201 LDO voltage regulator. The LP592201EVM contains one
LP592201DSC LDO adjustable voltage regulator, programmed to have an output voltage of 1.8 V, in the
WSON (DSC) package (see

Table 1

).
