Working Principles

The XC6121C632MR-G is a linear voltage regulator that operates by maintaining a constant output voltage regardless of changes in input voltage or load conditions. It achieves this through the use of a pass transistor and feedback circuitry. When the input voltage exceeds the desired output voltage, the pass transistor adjusts its resistance to maintain a stable output. Conversely, if the input voltage drops below the desired output voltage, the pass transistor increases its resistance to compensate.
