Current regulation and current limitation are not the same things. What you have described are probably Zener diodes like the IN 5256b 30v Zener I use which limits voltage not current. The current will still be whatever the load calls for. Current can be limited with a resistor but that's still not "current control". Current regulation or control can be done with two PnP transistors and a resistor or potentiometer.. I believe there is a chip available that does the job too [LM XXXX something or other] for under 2 bucks. Ken
