Working Principles

The RT9011-QQGQWC 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. The enable pin (EN) controls the operation of the regulator, allowing it to be turned on or off as needed.
