Working Principles

The S-1003NA40I-M5T1U is a low dropout voltage regulator that uses a PNP transistor as the pass element. It regulates the output voltage by adjusting the resistance between the input and output terminals. When the input voltage exceeds the desired output voltage, the pass element reduces the resistance to maintain a constant output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass element increases the resistance to compensate and maintain a stable output voltage.
