Introduction
The Texas Instruments TPS7A3301EVM-061 EVM helps design engineers to evaluate the operation and
performance of the TPS7A33xx family of linear regulators for possible use in their own circuit applications.
This particular EVM is preconfigured to output –15 V and contains a single linear regulator (LDO) with
internal current limit and thermal shutdown protection. The TPS7A33xx family of low-dropout regulators
allows input voltages from –3 V to –36 V and can be adjusted to any output voltage between –1.2 V and
–20 V by only changing a resistor value in accord with the given equation. The regulator, including
external components, is capable of delivering up to 1 A to the load depending on the input-output power
dissipation across the part. The TPS7A33xx has been optimized for ac performance, including PSRR and
load transient response, using capacitors rated over the full voltage range of the regulator. The
TPS7A33xx family is available in a TO220-7 KVT bent-lead package.

Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the TPS7A3301EVM.
2.1
Input/Output Connectors and Jumper Descriptions
J1 — (–)Vin
2.1.1
Negative input power supply voltage connector. The negative input lead and ground return lead from the
input power supply should be twisted and kept as short as possible to minimize EMI transmission.
Additional bulk capacitance should be added between J1 and J3 if the supply leads are greater than six
inches. For example, an additional 47-µF electrolytic capacitor connected from J1 to ground can improve
the transient response of the TPS7A3301 while eliminating unwanted ringing on the input due to long wire
connections. A (+) power supply may be used if the (+) lead is connected to J2 (GND) and the GND lead
is connected to J1 (–VIN).

Operation
•
•

Turn off the input power supply after verifying that its output voltage is set to greater than –15 V (–18 V
recommended; –36 V maximum). Connect the negative voltage lead from the input power supply to
–VIN, at the J1 connector of the EVM. Connect the ground lead from the input power supply to GND at
the J2 connector of the EVM. If using a (+) power supply, connect the (+) lead is to J2 (GND) and the
GND lead J1 (–VIN).
Connect desired (≤1 A) load between the –VOUT pin at connector J3, and the GND pin at connector
J4. Be careful to calculate the power dissipation across the part for the desired –VIN level.
Turn on the input power supply. For initial operation, it is recommended that the input power supply,
–VIN on J1, be set to –18 V.
Vary the load and –VIN voltage as necessary for test purposes.
Adjustable Operation
The nominal output voltage for the typical LDO circuit employing the TPS7A3301 is set by two external
resistors, R1and R2, as illustrated in Figure 1. R1 and R2 can be calculated for any output voltage using
Equation 1 and the Vref voltage found in the device data sheet under the Electrical Characteristics.

Once the resistor values have been calculated, the new resistors can be installed appropriately in the
correct place using the PCB and schematic diagrams of Figure 4 5 through Figure 7.
Suggestion: When recalculating the resistor values for a particular desired output voltage, change only the
R2 value in order to maintain the frequency-domain zero formed by R1 and CBYP in accord with
Equation 2.

Thermal Guidelines and Layout Recommendations
Thermal management is a key component of the design of any power converter and is especially
important when the power dissipation in the LDO is high. Use the following formula to approximate the
maximum power dissipation for the particular ambient temperature:
TJ = TA + PD ´ qJA
(3)
where TJ is the junction temperature, TA is the ambient temperature, PD is the power dissipation in the
device (watts), and θJA is the thermal resistance from junction to ambient. All temperatures are in degrees
Celsius. The maximum silicon junction temperature, TJ, must not be allowed to exceed 150°C. The layout
design must use copper trace and plane areas smartly, as thermal sinks, in order not to allow TJ to exceed
the absolute maximum rating under all temperature conditions and voltage conditions across the part. The
designer must consider carefully the thermal design of the PCB for optimal performance over temperature.
The actual allowable power dissipation on a PCB is a strong function of its layout.
Heat flows from the device to the ambient air through many paths, each of which represents resistance to
the heat flow; this resistance is called thermal resistance.
The total thermal resistance of a system is defined by Equation 4:
(T - TA )
qJA = J
PD
(4)
where θJA is the thermal resistance (in °C/W), TJ is the allowable junction temperature of the device (in
°C), TA is the maximum temperature of the ambient cooling air (in °C), and PD is the amount of power
(heat) generated by the device (in W).
Whenever a heatsink is installed, the total thermal resistance (θJA) is the sum of all the individual
resistances from the device, going through its case and heatsink to the ambient cooling air.
qJA = qJC + qCS + qSA
(5)
Realistically, the user can only control two resistances, θCS and θSA. Therefore, for a device with a known
θJC, θCS and θSA become the main design variables in selecting a heat sink.

The thermal interface between the case and the heat sink, θCS, is controlled by selecting the right heat
conducting material. Once the θCS is selected, the required thermal resistance from the heatsink to
ambient is calculated by Equation 6:
é (T - TA ) ù
qSA ê J
ú - (qJC + qCS )
ë PD
û
(6)
This information allows the user to select the most appropriate heatsink for any particular application.
The heat sink chosen for the TPS7A3301EVM-061 (507302B00000G from Aavid) has a specified thermal
resistance (θSA) of 24°C/W. There is also an option of using the two large mounting holes (13 and 14 –
see Figure 4) to mount a heat sink with a smaller thermal resistance. The mounting holes are sized for the
use of any heat sink with solderable mounting tab spacing of 1 inch (25.4 mm). The 5310 series from
Aavid is one example and has a specified thermal resistance (θSA) of 13.4°C/W.

EVALUATION BOARD/KIT/MODULE (EVM)
WARNINGS, RESTRICTIONS AND DISCLAIMERS
For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this EVM is not a finished
electrical equipment and not intended for consumer use. It is intended solely for use for preliminary feasibility evaluation in
laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks
associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end
product.
Your Sole Responsibility and Risk. You acknowledge, represent and agree that:
1.
2.

4.
You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug
Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees,
affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable
regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates,
contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical)
between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to
minimize the risk of electrical shock hazard.
You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even
if the EVM should fail to perform as described or expected.
You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials.
Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the
user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and
environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact
a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the
specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or
interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the
load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures
greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include
but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the
EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please
be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable
in electronic measurement and diagnostics normally found in development environments should use these EVMs.
Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives
harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in
connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims
arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected.
Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such
as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices
which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate
Assurance and Indemnity Agreement.

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
