Current Regulation - Diodes, Transistors

Current regulating diodes (also referred to a constand-current diode, current-limiting diode (CLD), or current-regulating diode (CRD)) maintain a constant current based on their specified value regardless of voltage fluctuations. Current regulating transistors work by regulating its collector and emitter voltage to provide a constant output voltage.
