I want to maintain the output voltage of a power supply even when a circuit wants to pull more current than a defined upper limit (so I don't want to pull the voltage down due to over current). I'd like to supply 20 V to a circuit, while only allowing a maximum current draw of 150 mA. The circuit will try to pull more current, but I want to observe its operation before the circuit's over current protection kicks in. Would this be best done with an active inrush current limiter? Any circuit/module suggestions?
