Part Number: TL783
Dear Kyle Van Renterghem and support member,
Because I can not reply the previous, I new post.
My customer made board of TL783.My customer make six parallel schematic Fig16 Current-Sinking Regulator.
I have a question.
Is there a way to control device variance by adding external configuration?
Best regard.Bob Lee.

Dear Mark Sellers,
Thank you very much for reply.
The configuration was described in the attached file.
Could you check attached file?
In reply to Bob Lee62837:
I designed that LED total current is 0.7 A.But I measured 0.71A.
The resistance of TL783 is 10.8Ω,and I considered 0.117 A for each IC.（LED total current is 0.117A x6 = 0.7A）
Even if each current is measured, it changes every time.
Is there a way to control by adding external configuration?
May I ask a question?
Your answer was replied as 1.5% LDO.Where it descript in the data sheet?
The accuracy is covered here. Your application may actually be at the 0.5% accuracy as you are using less than a 5V output. Hope this helps.
I tell my customer your addvice.I will feedback you.
