hello guys a lil bit help with variable power supply

[haprow]

I am looking for a good voltage regulator using a full discrete transistorized voltage regulator with current limiting ciruit..I have already  voltage regulator but if u guys know some workable regulator pls inform me but the most important is current limiter...guys!  help me to work with this project any suggestions or help maybe are very appreciated...next time i will send u my own volatege regulator without IC's...help me  ???

IC voltage regulators work very well and are inexpensive. You could copy their current-limiting circuit.
The 0V to 30V power supply in our projects section uses opamps to make current regulation.
