I am making a project which works on 3.3v. Here I am also using 6 digits 7-segment display so I need large current with 3.3V input.
I am using 6v of a battery which it needs to regulate and generate 3.3v. I have ld1117v33 and its max input voltage range is 15v. I also got some information about to give Vr = 1.25v.
Here I am confused how can I give Vr at which pin of ld1117v33. Please help me an understanding of Vr here and how it is different from Vin. Do I need to give separate voltage to Vr?
