Increase input voltage from 1v to about 1kV, you'll see it flatten out at around 4.8v on the blue trace... and remain pretty steady throughout. The green trace is a very simple buffer stage, nothing fancy; which is why it's a couple 10ths of a volt lower. I've ran into many complications trying to put together a voltage regulator circuit that could supply enough power without loading down too much on the buffer stage... come to find out, it was because I've been using a zener diode when I should've been using feedback, now that makes things a whole lot Less complicated to achieve even better results!
Thanks to Hurz! :)
