Hi Victor,
Thanks for reaching out! There are two p2p options I would like to highlight:
1.) If the output current capability of up to 100mA is required then please look into the TL431 (p2p packages: SOT23-3 & TO92-3)
2.) If output current requirement…
Part Number: TPS23753A Other Parts Discussed in Thread: PMP8803 , TL431LI Hi,
Is it possible to use TL431LIBCDBZ as an alternative to U3 TL431ACDBVR in PMP8803?
I'm using the TL431LI part elsewhere in my design so I'd like to use this throughout. With the…
Part Number: TL431 Other Parts Discussed in Thread: TLVH431 , ,
Do you have a simple device nomenclature guide for shunt references such as (A)TL431, (A)TL431LI, TLVH431 and others?
Willem,
The TL431LI is an improved version of the TL431 and should be a drop-in replacement in the SOT-23-3 package.
Is the optocoupler the "A" version with the 80-160% CTR?
Check the value of the resistor in series with the opto diode.
Thanks…
Hello Sasaki-san,
Thank you for your question.
The customer should use the "2V" factor in Equation (33) exactly as it is; neither increasing or decreasing it. This is true for both TL431B and TL431LIB.
The factor "2V" comes from the datasheets…
Hi Philip,
Since ceramic capacitors have low ESRs, you can add a small amount of resistance in series with the capacitor. The capacitor is connected from the cathode to the anode of the TL431. I have included a link for you for your reference:

Part Number: TL432LI-Q1 Other Parts Discussed in Thread: TL431LI Hello,
Can you confirm the cathode current requirement (IKA) at VKA > VREF working condition? Is this 1mA? Also provides the calculation for finding Vref for this application
Regards, …
Hi Ben, Thanks - I am currently looking at the TL431LI due to availability reasons - it looks like this also has a better stability region but I assume I'll need some additional ESR.
Thank you for the help :).
Many thanks
Part Number: ATL432LI Other Parts Discussed in Thread: ATL431LI , ATL431 , TL431LI Hi,
My customer would check the IKA between TI ATL431LI and diode AS431
There have differences between ATL431 and AS431 IKA, you can see in the following table.
Will it cause…
Part Number: LMV431 Other Parts Discussed in Thread: TINA-TI , TL431LI Hello,
I've played around with this and haven't come up with a good solution yet. I have a project that is battery powered (nominal 12V - 24V) but when the battery is removed I want…
