Has anyone perchance used the AD797 with TL431-based shunt regulation (either with or with auxiliary current booster)?

I've previously used the 797 mainly with series IC regulators (for instance, 317/337, LT1086/LT833) without noting any stability or sonic problems (assuredly with local capacitive bypassing at the load), and now I would like to try IC-based shunt regulation.

However, studying the data sheet of the 431 reveals that the output impedance rises steadily above 50kHz until it hits about 13~14 ohms in the 1~5MHz region. I am interested in knowing if this impedance will pose problems for the AD797, and likewise if local capacitive bypasses to ground at the 797's power supply pins will be sufficient to keep it stable and well-mannered.

Any experience or thoughts will be appreciated.

regards, jonathan carr

Your limiting factor in this rig will end up being the DD TT.
