hello board, I want to regulate a SMPS which works @100kHz(~4A), I first look at lm338 that was terrible @100kHz even @10kHz so I ruled it out, then I remembered old good 723. I could not find the information I needed in datasheet, it says @10kHz ripple rejection is amazing 86db, well but what it would be around 100kHz? there was no graph. I can accept even 20db fall in 100kHz even 66 db is quite good for me. dose anybody have experience with 723 @HF? any rough estimate?
