Working Principles

The S-1315A12-M5T1U3 is a linear voltage regulator that operates by maintaining a constant output voltage regardless of changes 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 current to flow and maintaining a steady output voltage. Conversely, when the input voltage drops below the desired output voltage, the pass transistor increases its resistance, allowing more current to flow and again maintaining a constant output voltage.
