My Voltage Regulatro based on LD1117

[zihao]

Good day,friends

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.
The datasheet ofLD1117V33
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?

Thanks a million,
Best wishes~

I think you're on the wrong forum. Try stackexchange?
It's a pretty simple 3-pin voltage regulator though. Look at page 6 and page 8 of the data sheet. It has examples. For the fixed output you won't need the resistor, just capacitors.

Now unless you own an XS400 that's probably all the help you'll get here.
