Hi Team,
A customer is using TL431BIPK,
for noise (Radiance immunity), how to design the circuit around TL431BIPK?
To make the noise performance will be improved.
I read some posts about to add bypass cap for this device, is it OK for 10uF and 0.1uF?
Do you have a circuit to show where the bypass cap should be added?
can you share me the circuit?
BTW, Do you have any other suggestions?
Thanks.
Hi Frank,
Thanks for your question. I would recommend reviewing Figure 18 in the datasheet to understand the caps requirement for your design.
Other design resources are:
Designing with the "Advanced" TL431, ATL431
Understanding Stability Boundary Conditions Charts in TL431, TL432 Data Sheet

Hi Frank,
Please add the bypass caps from Cathode to ground as show in Figure 18.
