Working Principles

The RT9011-FMGQW operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. When the input voltage exceeds the desired output voltage, the pass transistor adjusts its resistance to maintain a stable output voltage. Conversely, if the input voltage drops below the desired output voltage, the pass transistor reduces its resistance to compensate and provide a regulated output.
