Working Principles

The 72V221L10PF8 is a linear voltage regulator that utilizes a feedback mechanism to maintain a stable output voltage. It compares the actual output voltage with a reference voltage and adjusts the internal circuitry accordingly. When the input voltage exceeds the desired output voltage, the regulator reduces it to the required level. Conversely, if the input voltage drops below the desired output voltage, the regulator boosts it to maintain a constant output.
