Part Number:TL431A
Hi,
Could you tell me about the stability of TL431A.
I analyzed AC circuit of customers using TINA-TI.
The simulation results are attached below.
(Please visit the site to view this file)
From Figure 16 of datasheet P.16, the phase margin is low even under "Stable" condition (CL = 5 μF),
so I think that the result of AC analysis is not correct.
Do I mistake the way of simulation?
Or is there a mistake in the circuit?
I would be appreciate if you give me advice.
Best regards,
Yuto Sakai
