Hello Ulrich,
Thanks for the detailed explanation. I think first testing with LMV431 is a better option for now, as it will reduce addition of any components.
Thanks and Regards,
Raj
Other Parts Discussed in Thread: LMV431 We got a new batch of chips LMV431. Driving behavior has changed.
Also, the new devices have a larger size.
Got a question. ICs of the new party are normal or is it counterfeit?
after reading many datasheets of 431 famility finally added a cap from pass FET to ground to solve this problem. actually this can also be solved by putting a cap at reference divider to ground.
Part Number: TLV431 Other Parts Discussed in Thread: LMV431 Hello everyone,
I am facing a problem in the start-up of a TLV431 used as a comparator. In my application, I use a TLV431BCDBZR as a comparator to sense when the voltage across the resistance…
Hello Suja,
The closest alternative would be the TLVH431 series which has a rating of 18V vs 30V on LMV431. Hope this works.

Thanks.
What is the max voltage on the input Vref (while V cathode is 0v)
I would like to know if the situation when Vref existing, While the V cathode is 0v is legal?
Part Number: UCC28951 Other Parts Discussed in Thread: AMC1311 , LMV431 , UCC28950 Hello,
I'm thinking of using a photocoupler to isolate the output voltage and feed it back, where should I put the photocoupler?
I am thinking of putting it on the red…
Other Parts Discussed in Thread: LMV431 , LM3481 Alan, All,
Note the LMV431 here in your circuit, that device is a zener 3 pin not a five pin op-amp as shown here correct, I'm confused?. I have implimented a similair circuit using the LM3481 as suggested…
Hi Martin,
This situation seemed a bit odd. I went to test it and validated with others.
There is 3 states for the LMV431.
Vref < 1.24V -> Vka = Vcc
Vref = 1.4V -> Vka = 1.24V
Vref > 1.24V -> Vka = 1V and increases linearly to Vref and…
