TLV751-EVM Evaluation Module

1

Introduction

Texas Instruments' TLV751-EVM helps design engineers evaluate the operation and performance of the
TLV751 family of linear regulators for possible use in their own circuit application. This particular EVM
configuration contains a single high-accuracy, small size, dual-input linear regulator for a wide range of
applications. The regulator is capable of delivering up to 500 mA to the load for each input channel with
low V

IN

to V

OUT

dropout voltage. For stability, use a minimum derated capacitance of 0.47-µF (or larger)

output capacitor for each output channel.

Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the
TLV751-EVM. Observe all safety precautions.

Warning

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

CAUTION

The circuit module can 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
you are 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.
