TPS7A52EVM-031 Evaluation Module

1

Introduction

Texas Instruments' TPS7A52EVM-031 EVM helps design engineers evaluate the operation and
performance of the TPS7A5201RPS device for possible use in a circuit application. This particular EVM
configuration contains a single low-noise, high-PSRR linear regulator for radar applications. The regulator
is capable of delivering up to 4 A to the load with ultra-low VIN to VOUT dropout voltage. For stability, use
a 47-µF (or larger) output capacitor for the TPS7A52EVM-031.

1.1

Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the
TPS7A52EVM-031. Observe all safety precautions.

Warning

Warning Hot surface. Contact may cause burns. Do not touch.

CAUTION

The circuit module may be damaged by overtemperature. To avoid damage,
monitor the temperature during evaluation and provide cooling, as needed, for
your system environment.

CAUTION

Some power supplies can be damaged by application of external voltages. If
using more than one power supply, check your equipment requirements and
use blocking diodes or other isolation techniques, as needed, to prevent
damage to your equipment.

CAUTION

The circuit module is not a finished product or electrical appliance. The module
does not contain current or voltage thresholds for circuit protection. It must be
used by qualified personnel with additional equipment for evaluation only.
