Voltage Regulator square to dc

Square to DC of my own design, but it is a bit clunky; the pot isn't changing the output voltage as i'd like... 

World love it if i could get some help from this nice community. A workaround perhaps? Cheers!

Try to rectify the square wave via a single half wave rectifying diode or via a full wave bridge. Then you move the capacitor you've got on the output side on the regulator to the input side. That way you got a more noisy DC on the input instead of a square wave. The regulator works best if the input voltage is above the output voltage by some amount all the time. Try to change the load resistor to some smaller values to see how the load regulation is working out ;)

That is actually of great help sir! The output, originally, was supposed to vary according to some guidelines but that can easily be tuned through playing around with pot values and / or other resistors in series.

Also, another one of the points i needed to hit was thermal efficiency, by that i mean as little voltage variance due to ambient temperature as possible. Without going too much into detail, how would i go about in doing that?
