Working Principles

The S-1701Q3315-M5T1G operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. When the input voltage exceeds the desired output voltage, the pass transistor adjusts its resistance to reduce the voltage difference. Conversely, if the input voltage drops below the desired output voltage, the pass transistor increases its resistance to compensate and maintain a stable output voltage.
