Working Principles

The S-1112B28PI-L6NTFU is a linear voltage regulator that operates by maintaining a constant output voltage regardless of variations in the input voltage. It achieves this through the use of an internal voltage reference and feedback control mechanism. When the input voltage exceeds the desired output voltage, the regulator reduces the voltage to maintain a stable output. Conversely, if the input voltage drops below the desired output voltage, the regulator compensates by increasing the voltage.
