Working Principle

The SPX1117M3-L-5-0 is a linear voltage regulator that works by comparing an external reference voltage to an internal reference voltage and then controlling an internal pass transistor in order to maintain a constant output voltage. The transistor’s base is connected to the internal reference voltage and its emitter is connected to ground. The collector of the transistor is connected to the output voltage and is also connected to the adjustable voltage divider circuit. The voltage divider circuit allows users to adjust the output voltage of the regulator by changing the ratio between the two resistors. When the external reference voltage rises, the current through the pass transistor increases and the output voltage of the regulator decreases. Conversely, when the external reference voltage falls, the current through the pass transistor decreases and the output voltage of the regulator increases.
