Working Principles

The S-1315C41-A6T2U3 is a low dropout regulator that regulates the output voltage by maintaining a constant voltage difference between the input and output. It achieves this by using a pass transistor and feedback circuitry to adjust the output voltage based on the reference voltage.

When the input voltage is higher than the desired output voltage, the pass transistor remains in the "on" state, allowing current to flow from the input to the output. As the input voltage decreases or approaches the desired output voltage, the pass transistor adjusts its resistance to maintain a stable output voltage.
