Part Number: TL431LI Other Parts Discussed in Thread: TL431 , ATL431 Hello,
my question is maybe Kind of stupid but please forgive me for that, but I'm curious ;-)
Why is it that there are *431* references on the market which have 2.5V as there nominal…
Hi,
This looks like a simulation error as it's impossible for voltage and current to be constant with a changing resistance.
I tested this circuit on the bench with the TL431LI and achieved a constant 1mA current. The output voltage changed with PT1000…
Hi Given,
I don't see anything too different with the devices:
Could you have them check circuit with the TL431LI?

Part Number: LMV431B Other Parts Discussed in Thread: TL431LI , TLVH431 , LMV431 Hi,
I'm trying to find alternates for the PN: LMV431BIMF/NOPB. This part has the voltage reference of 1.24V.
But the part which I found as alternate has the Voltage reference…

What is the recommended operating condition for refernce pin of shunt regulators { TL431/ATL431/TL431LI/ATL431LI/TLV431/ATL431LI}?
Hello Tim,
My response would be the same. You are operating the device outside of its spec range. You may want to consider a device designed for a wider operating range such as the TL431LI.

Hi Alan
TL431 is not stable at 0.1uF capacitor at 10mA current. Please change the C80 as per figure 7-18 (Page -18) in the data sheet and app note SLVA482A . It will be stable. It will be stable without any load capacitor (this is optional for you.)
I believe…
