AnalogKid Well-Known Member Most Helpful Member Jun 28, 2022 #2 The reference designator "VR1" tells me it is a voltage reference or regulator of some kind, maybe a shunt regulator like a TL431, or any of a zillion active voltage references. ak Upvote 0 Downvote

D Diver300 Well-Known Member Most Helpful Member Jun 28, 2022 #3 I also think that it's a TL431 or equivalent. Is it in a switch-mode power supply? A lot of those use TL431or similar for the voltage feedback. Upvote 0 Downvote
