I am trying to build the following circuit but I am confused on how it works, and how the unlabeled passive components are sized. If I understand correctly, when…
Part Number: LM431 Tool/software: Hi team
I want to generate a regulated voltage output based on LM431, could I use following circuit directly?
And for the Vz calculation equation, should I take Vref as 2.495V and Iref as 2uA as below EC table?
If…

Team,
Customer is using the LM431 (LM431BIM3/NOPB) on an AC/DC (PFC flyback: 1Ph 230V AC to 24V DC 5A with PFC voltage: 390V). The LM431 is used for the feedback sensing on the secondary side.…
Other Parts Discussed in Thread: LM431 Hello Support Team,
My customer is aksing what is Tj of LM431 since there is no description on the datashhet. I guess TI does not have Ti value to share with customer and Tj should be calcurated by customer basied…
Part Number: LM431 Dear Team,
Is the only difference between LM431AIM3 and LM431AIM3/NOPB the availability of RoHS support?
My understanding is that there is no difference in the respective characteristics of both products.
Is my understanding about that…
Part Number: LM431 Other Parts Discussed in Thread: TL431 Hello,
I have a circuit challenge.
The voltage should be limited at a high-impedance ADC input without influencing the high-impedance measurement signal.
The problem should be solved with a shunt…
