TLVH431 family  
NXP Semiconductors  
Low voltage adjustable precision shunt regulators  
7. Functional diagram  
The TLVH431 family comprises a range of 3-terminal adjustable shunt regulators, with  
specified thermal stability over applicable automotive and commercial temperature  
ranges. The output voltage can be set to any value between Vref (approximately 1.24 V)  
and 18 V with two external resistors (see Figure 10). These devices have a typical output  
impedance of 0.1 . Active output circuitry provides a very sharp turn-on characteristic,  
making these devices excellent replacements for Zener diodes in many applications like  
on-board regulation, adjustable power supplies and switching power supplies.

Figure 21, 22 and 23 show the stability boundaries and test circuits for the worst case  
conditions with a load capacitance mounted as close as possible to the device. The  
required load capacitance for stable operation varies depending on the operating  
temperature and capacitor Equivalent Series Resistance (ESR). Verify that the application  
circuit is stable over the anticipated operating current and temperature ranges.

Please consult the most recently issued document before initiating or completing a design.  
The term ‘short data sheet’ is explained in section “Definitions”.  
The product status of device(s) described in this document may have changed since this document was published and may differ in case of multiple devices. The latest product status  
information is available on the Internet at URL http://www.nxp.com.  
Suitability for use — NXP Semiconductors products are not designed,  
19.2 Definitions  
authorized or warranted to be suitable for use in life support, life-critical or  
safety-critical systems or equipment, nor in applications where failure or  
malfunction of an NXP Semiconductors product can reasonably be expected  
to result in personal injury, death or severe property or environmental  
damage. NXP Semiconductors and its suppliers accept no liability for  
inclusion and/or use of NXP Semiconductors products in such equipment or  
applications and therefore such inclusion and/or use is at the customer’s own  
risk.  
Draft — The document is a draft version only. The content is still under  
internal review and subject to formal approval, which may result in  
modifications or additions. NXP Semiconductors does not give any  
representations or warranties as to the accuracy or completeness of  
information included herein and shall have no liability for the consequences of  
use of such information.  
Short data sheet — A short data sheet is an extract from a full data sheet  
with the same product type number(s) and title. A short data sheet is intended  
for quick reference only and should not be relied upon to contain detailed and  
full information. For detailed and full information see the relevant full data  
sheet, which is available on request via the local NXP Semiconductors sales  
office. In case of any inconsistency or conflict with the short data sheet, the  
full data sheet shall prevail.  
Applications — Applications that are described herein for any of these  
products are for illustrative purposes only. NXP Semiconductors makes no  
representation or warranty that such applications will be suitable for the  
specified use without further testing or modification.  
Customers are responsible for the design and operation of their applications  
and products using NXP Semiconductors products, and NXP Semiconductors  
accepts no liability for any assistance with applications or customer product  
design. It is customer’s sole responsibility to determine whether the NXP  
Semiconductors product is suitable and fit for the customer’s applications and  
products planned, as well as for the planned application and use of  
customer’s third party customer(s). Customers should provide appropriate  
design and operating safeguards to minimize the risks associated with their  
applications and products.  
Product specification — The information and data provided in a Product  
data sheet shall define the specification of the product as agreed between  
NXP Semiconductors and its customer, unless NXP Semiconductors and  
customer have explicitly agreed otherwise in writing. In no event however,  
shall an agreement be valid in which the NXP Semiconductors product is  
deemed to offer functions and qualities beyond those described in the  
Product data sheet.  
NXP Semiconductors does not accept any liability related to any default,  
damage, costs or problem which is based on any weakness or default in the  
customer’s applications or products, or the application or use by customer’s  
third party customer(s). Customer is responsible for doing all necessary  
testing for the customer’s applications and products using NXP  
Semiconductors products in order to avoid a default of the applications and  
the products or of the application or use by customer’s third party  
customer(s). NXP does not accept any liability in this respect.  
19.3 Disclaimers  
Limited warranty and liability — Information in this document is believed to  
be accurate and reliable. However, NXP Semiconductors does not give any  
representations or warranties, expressed or implied, as to the accuracy or  
completeness of such information and shall have no liability for the  
consequences of use of such information. NXP Semiconductors takes no  
responsibility for the content in this document if provided by an information  
source outside of NXP Semiconductors.  
Limiting values — Stress above one or more limiting values (as defined in  
the Absolute Maximum Ratings System of IEC 60134) will cause permanent  
damage to the device. Limiting values are stress ratings only and (proper)  
operation of the device at these or any other conditions above those given in  
the Recommended operating conditions section (if present) or the  
Characteristics sections of this document is not warranted. Constant or  
repeated exposure to limiting values will permanently and irreversibly affect  
the quality and reliability of the device.  
In no event shall NXP Semiconductors be liable for any indirect, incidental,  
punitive, special or consequential damages (including - without limitation - lost  
profits, lost savings, business interruption, costs related to the removal or  
replacement of any products or rework charges) whether or not such  
damages are based on tort (including negligence), warranty, breach of  
contract or any other legal theory.  
Terms and conditions of commercial sale — NXP Semiconductors  
products are sold subject to the general terms and conditions of commercial  
sale, as published at http://www.nxp.com/profile/terms, unless otherwise  
agreed in a valid written individual agreement. In case an individual  
agreement is concluded only the terms and conditions of the respective  
agreement shall apply. NXP Semiconductors hereby expressly objects to  
applying the customer’s general terms and conditions with regard to the  
purchase of NXP Semiconductors products by customer.  
Notwithstanding any damages that customer might incur for any reason  
whatsoever, NXP Semiconductors’ aggregate and cumulative liability towards  
customer for the products described herein shall be limited in accordance  
with the Terms and conditions of commercial sale of NXP Semiconductors.  
Right to make changes — NXP Semiconductors reserves the right to make  
changes to information published in this document, including without  
limitation specifications and product descriptions, at any time and without  
notice. This document supersedes and replaces all information supplied prior  
to the publication hereof.  
No offer to sell or license — Nothing in this document may be interpreted or  
construed as an offer to sell products that is open for acceptance or the grant,  
conveyance or implication of any license under any copyrights, patents or  
other industrial or intellectual property rights.
