Working Principles

The PQ1R28 is a linear voltage regulator that maintains a constant output voltage regardless of variations in the input voltage or load conditions. It achieves this by using a pass transistor to regulate the output voltage based on a feedback mechanism. The regulator compares the output voltage with a reference voltage and adjusts the pass transistor accordingly to maintain the desired output voltage.
