TPS7A89 Evaluation Module
1 Introduction
The Texas Instruments TPS7A8901EVM-853 EVM helps design engineers evaluate the operation and
performance of the TPS7A89 linear regulator for possible use in their own circuit application. This
particular EVM configuration contains a dual low-noise, high-PSRR linear regulator, ideal for high-
performance signal chain. The regulator is capable of delivering up to 2 A per channel to each load with
low dropout (VIN – VOUT) voltage for high-efficiency operation. For stability, each channel requires a 10-
µF input capacitor and 10-µF output capacitor for the TPS7A89.
1.1 Before You Begin
The following warnings and cautions are noted for the safety of anyone using or working close to the
TPS7A8901EVM-853. Observe all safety precautions.
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.

2 EVM Setup
This section describes how to properly connect and setup the TPS7A8901EVM-853, including the jumpers
and connectors on the EVM board.
2.1 Input/Output Connectors and Jumper Descriptions
2.1.1 J1 – VIN1
Channel-1, input power-supply voltage connector. Twist together the positive input lead and ground return
lead from the input power supply; keep the leads as short as possible to minimize input wire inductance.
Add additional bulk capacitance between J1 and J4 (use the C1 footprint) if the supply leads are longer
than six inches. For example, an additional 47-µF electrolytic capacitor connected from J1 to ground
improves the transient response of the TPS7A89, while eliminating unwanted ringing on the input because
of long wire connections.
2.1.2 J2 – VOUT1
Channel-1, regulated, output voltage connector.
2.1.3 J3 – VPU1
Channel-1, pullup-voltage selector for PG1. This EVM is designed so that PG1 can be pulled up to either
VOUT1 by shorting J3, or pulled up to another voltage by applying an external voltage to the RPU1 post.
2.1.4 J4 – GND
Return connector for the channel-1, input power supply.
2.1.5 J5 – GND
Channel-1, output, ground return connector.
2.1.6 J6 – VIN2
Channel-2, input, power-supply voltage connector. Twist together the positive input lead and ground return
lead from the input power supply; keep the leads as short as possible to minimize input wire inductance.
Add additional bulk capacitance between J6 and J8 (use the C9 footprint) if the supply leads are longer
than six inches. For example, an additional 47-µF electrolytic capacitor connected from J6 to ground
improves the transient response of the TPS7A89, while eliminating unwanted ringing on the input because
of long wire connections.
2.1.7 J7 – VOUT2
Channel-2, regulated, output voltage connector.
2.1.8 J8 – GND
Return connector for the channel-2, input power supply.
2.1.9 J9 – GND
Channel-2, output, ground return connector.
2.1.10 J10 – ANYOUT2
The channel-2 output voltage of the TPS7A89 is selectable in accordance with the names given to the
output voltage setting pins: 50 mV, 100 mV, 200 mV, 400 mV, 800 mV, 1.6 V, and 1.6 V. For each pin
connected to the ground, the output voltage setting increases by the value associated with that pin name,
starting from the value of the reference voltage of 0.8 V; floating the pins has no effect on the output
voltage.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
