Part Number: LM431 Hello TI Team,
Checking the datasheet of part LM431AIM3X/NOPB , I found the R θJA (Junction-to-ambient thermal resistance) value on section 6.4 Thermal Information. However, it did not mentioned anything about the test board used…
Hi Maxime,
The ones that are under National are LM431 and MM54, both of these are obsolete.
Alternates:
LM431: This product family still exists. we offer other accuracy options with the same pin out. Please see https://www.ti.com/product/LM431
MM54 is…

Part Number: LM431 Hello.
In our project, which is on mass production stage already, we applied LM431BIM3N1C.
Now LM431BIM3N1C is NRND-device, and it's replaced by LM431BIM3/NOPB.
What are the HW differences between these two devices, and what are the…
Part Number: LM431 Other Parts Discussed in Thread: TL431 , Can someone help me to get the anode to cathode voltage of LM431A in comparator mode of operation?
Thanks in advance.

Part Number: LM431 Other Parts Discussed in Thread: LM324 , TPS3711 Hello
I am using the LM431, works well at 14V, I get a 1 volt difference between Vin and Vo with Iz less than 5 mA, everything is ok
BUT, at 28V, impossible to goi down 50 mA for Iz (…
Hi Jeoun,
Your UCC5390 has a Vee = -5V and Vcc=20V. Are you sure you don't want to make these -3V and 18V also? That will greatly simplify the design.
Below is a achematic example of a Zener diode based bipolar supply. You can get more voltage accuracy…
