1 Introduction

The Texas Instruments TPS7A53EVM-080 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS7A53A-Q1 LDO voltage regulator. As shown in Table 1-1, the TPS7A53EVM-080 contains one TPS7A53A-Q1 LDO voltage regulator in the RTJ package. An optional load transient circuit is also included to assist the user with high-speed load transient testing. To simplify current measurements, an input current loop is included.
