Hi Isaac,
Thanks for your reply. We need to know the TLV431A's cathode voltage for this calculation as you mentioned. I will reopen your question and forward your question to the PMIC team and hope they are more familiar with TLV431A.
Please do not…
Part Number: TLV431A-Q1 Other Parts Discussed in Thread: TLV431 Hi Team,
Is there by chance any sort of tiny evaluation module for these little shunt regulators? At the minimum, is there some sort of DIP package adapter?
Thank you,
Jared
The TLV431A and TLVH431A have 1 %; the TLV431B, 0.5 %. Prices and availability depend on the package; which one do you need?
(Series references like the REF3012 are more expensive.)
Part Number: TLV431A Hi ,
My customer is using TLV431AIDBZR , so we supplied them in the month of Sept-16 @2500 Nos.
They took part in production and It is observed that IC (TLV431A1 shunt regulator IC) pins having solderability problem.
Observations:…

Hi,
We got a question from customer about TLV431AIDBV. Could you help us?
[Question] They consider to use DBV PKG. If NC pin (pin 1 and pin 2) is connected to GND, is there any concerns?

Hi Sivakumar,
1. Could you try to measure the voltage at R44? This should be 1.24 V.
Only 0.4V is getting at this point.
Seems the TLV431A related circuit has some issues, so it cannot present the correct 1.24 V. It could be the main reason to give you…
Hello Fred,
Yes, it is the same as that circuit. The advantage of the TLV431 is the output is very accurate with low temperature drift. The output voltage accuracy for the TLV431A is 1% at 25C. The temperature drift is also very small.
Best,
Walter

Hello
I have something wrong with TLV431A;
I use it as the reference voltage IC to a DDR IC, and have a filter capacitor of 0,1uF/16V 0402 between GND and pin 1(REF), our package is SOT-23-3
In that case ,there is…
Hi Tommy,
While the CAD symbols are not available from us for all the parts on this PMP project, you can attain the CAD symbols for all the TI parts.
