Working Principles

The MAX6106EUR+T is a linear voltage regulator that uses a feedback mechanism to maintain a stable output voltage. The feedback pin (FB) is connected to a resistive voltage divider network, allowing the user to set the desired output voltage. The regulator compares the feedback voltage with an internal reference voltage and adjusts the pass transistor accordingly to maintain the desired output voltage.
