Simple Current Limit Circuit using Transistors
... The above circuit will act like a normal switch as long as the load doesn't try and draw too much current. If the load tries to draw too much current (50mA in this case) Q2 will divert some of the current away from Q1 and Q1 will increase the collector emitter voltage drop until the current is stabl ...
