Page 3: Introduction
Introduction Texas Instruments' TPS746EVM-009 EVM helps design engineers evaluate the operation and performance of the TPS746 family of linear regulators for possible use in their own circuit application. This particular EVM configuration contains a single low-noise, high-PSRR linear regulator for high-speed communication systems.

EVM Setup www.ti.com EVM Setup This section describes how to properly connect and setup the TPS746EVM-009, including the jumpers and connectors on the EVM board. Input/Output Connector and Jumper Descriptions 2.1.1 J1 – IN Input power-supply voltage connector. Twist together the positive input lead and ground return lead from the input power supply, and keep them as short as possible to minimize input inductance.
