Working Principles

The MX7535KP+T is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the reference voltage with a fraction of the output voltage through a feedback network. The error amplifier adjusts the pass transistor to maintain the desired output voltage, compensating for load and line variations.
