TLV431 Description
The TLV431 is a three-terminal, adjustable shunt regulator offering excellent temperature stability and output current handling capability up to 20mA. The output voltage may be set to any chosen voltage between 1.24V and 18V by selection of two external divider resistors. The TLV431 can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance. The TLV431 is available in three grades with initial tolerances of 1%, 0.5%, and 0.2% for the A, B, and T grades respectively.

Frequently Asked Questions
1.What is the difference between TL431 and TLV431
The TL431 is the original standard shunt voltage reference.
The TLV431 is a lower voltage reference option of the TLV but also has some different specifications.
2.What is the difference between LMV431 and TLV431?
The LMV431 is what device was developed by the previous National Semiconductor team and is a functional equivalent to the TLV431, although the LMV431 has a higher tolerance at the cathode for high voltage. The same is true for the LM431 vs TL431, these are direct functional equivalents.
3.As circuit breakers are used for over current protection, which device is used for over voltage protection?
Transient suppressors are good for ESD protection.Use the clamping diode for signal over voltage protection.Design the circuit for over voltage protection using comparator's, reference generator along with latch circuit. I designed the over voltage protection circuit using TLV431.
