Part Number: TLV431A-Q1
Hi Experts,I would like to use Figure 35 of datasheet. Then I would like to know whether there are any limitation of capacitor value for Vi(bat) and Vo. Should I refer to figure 12&13 for stability concern? Do you have a graph of stability boundary condition for figure 35?Your support would be much appreciated.Best Regards,Fujiwara
Can you clarify what you mean by Figure 35? There is no such figure in the datasheet for the TLV431A-Q1 on ti.com.

Abhinav-san,Sorry, I posted in Japanese.I have mistaken a device name, correct one is "TL431A-Q1". The Figure 35 is below. I would like to use Figure 35 of datasheet. Then I would like to know whether there are any limitation of capacitor value for Vi(bat) and Vo. Should I refer to figure 12&13 for stability concern? Do you have a graph of stability boundary condition for figure 35?Best Regards,Fujiwara
While we don't have a graph for the stability boundary condition for the circuit in Figure 35, we have a note in section 8.3 of the datasheet that points you to Figure 24 to use as a guide to help selecting an output capacitor as you can see the detailed schematic. In addition, you should be able to refer to Figure 12/13 to analyze stability boundary conditions for load capacitance vs cathode current.
Let me know if you have any more questions.
