Working Principles

The RT9166A-12GGL is a linear voltage regulator that maintains a constant output voltage despite variations in input voltage and load conditions. It achieves this by using a pass transistor to regulate the output voltage based on a feedback mechanism. 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 and provide a consistent output.
