Working Principle

IRU1205-33CLTR operates on the principle of Linear Voltage Regulation. It works by acting as a bridge between two circuits, one regulating the input voltage, the other regulating the output voltage. The output voltage is derived by indirectly controlling the circuit’s input voltage using the negative feedback system. It monitors the difference between the input and output voltages and adjusts the resistance of the transistor in order to maintain the required output voltage. This resistance change in the transistor helps managing the output voltage.
