Need an overview to replace fixed voltage reg with adjustable voltage reg,




Is there any info that run through this in layman's terms?

I'm somewhat confused as to what the value of Vref would be.

-Vout I want 15v,
-Vin is around 18v.
-R1 I'll use 100ohm (I have one lying around).
-Iadj is small, so I'm ignoring the Iadj*R2

Thanks
Cleet
