Working Principles

The L7806CD2T is a linear voltage regulator that uses a series pass transistor to regulate the output voltage. It operates by comparing the reference voltage with a fraction of the output voltage, adjusting the pass transistor's resistance to maintain a constant output voltage. The excess voltage is dissipated as heat, which is why the device may require additional cooling measures in high-power applications.
