Working Principles

The RT9073A-20GQZ is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage to control the pass transistor's conduction. The enable pin (EN) allows for turning the regulator on or off.

When the input voltage (VIN) is within the specified range, the regulator maintains a stable output voltage (VOUT) by adjusting the pass transistor's resistance. If the output voltage deviates from the desired value, the feedback mechanism adjusts the pass transistor to bring it back to the set point.
