Hi Ugly
Ok, you've lost me.
Why is a voltage divider calc relevant to calculating R values in a adjustable voltage reg? Input voltage is not relevant other than not going to below the dropout voltage or exceeding the max Vin right?
Apologies for the questions, but I new at this.
But to your point, np, I can substitute the 100ohm for the R2 spot.
Regards
Paul
