I have read some articles on on the following circuit. I was wondering if I can create such a Voltage and Constant Current Regulator for my Power Supply or not.
My Question is - is this circuit Practical? And will 1 Watt power rating's Variable Resistances and 2 Watt Ratings Resistances work?
Here the first LM317 is used as Current Regulator and the Second one as Voltage Regulator. I was also wondering if this ordering is correct, or if this has to be reversed - i.e. first voltage regulator and then Current Regulator to make it work better. Please help.
PS: I need this circuit to regulate Voltage and keep the output current to a configurable Constant level.
