Adjusting the fixed (3 terminal) voltage regulators

extends:: Adjusting the adjustable voltage regulator , Apr 5, 2015

(Std./)Simple v. :


with LT1086 (1.24V - adjustable) it gives seemingly errorless output ?

Op. Amp. v. :


it looks it is impossible to gain the ±2µV error level with just the one op-amp ►►
(the reference must be flawless as it shows on the graph. ???)
The Red LED-s are so cool for voltage adjustment -- their non-linear range begins below 275µA , they have sharper "turn on" than conventional detergents -- which puts them to (Diode,Stabistor,Red-LED,Zener Diode) this position - i assume . . .

Update :: 2016-03-11 ► Insane :

 
seemingly "absolute" voltage reference at 1 Hz
