TPS7B81EVM-025 Evaluation module
1
Introduction
Texas Instruments' TPS7B81EVM-025 EVM helps design engineers evaluate the operation and
performance of the TPS7B81-Q1 family of linear regulators for possible use in their own circuit application.
This particular EVM configuration contains a single 150-mA high-voltage, ultralow-IQ, low-dropout
regulator for automotive systems. The regulator is capable of delivering up to 150 mA to the load with a
wide V
IN
range of up to 40 V (45 V transient). For stability, use a 2.2-µF (or larger) output capacitor for the
TPS7B81-Q1.

Before You Begin
The following warnings and cautions are noted for the safety of anyone using or working close to the
TPS7B81EVM-025. 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. This
module must be used by qualified personnel with additional equipment for
evaluation only.
