2 Introduction

The Texas Instruments TPS7A21EVM-059 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS7A21 LDO voltage regulator. As shown in Table 2-1, the TPS7A21EVM-059 contains one TPS7A21 LDO voltage regulator in the DSBGA package. An optional load transient circuit is also included to assist the user with high-speed load transient testing. An input current loop is included that allows fast measurements of the input current.
