Working Principles

The S-1315A20-A6T2U3 is a linear voltage regulator that operates by maintaining a constant output voltage regardless of variations in the input voltage or load conditions. It achieves this through the use of a pass transistor that adjusts its resistance to regulate the output voltage.

When the input voltage exceeds the desired output voltage, the pass transistor reduces its resistance, allowing less voltage to pass through and maintain the desired output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its resistance, compensating for the difference and ensuring a stable output voltage.
