Working Principles

The NCV7805BDTRKG is a linear voltage regulator based on the fixed output voltage principle. It utilizes a series pass transistor to regulate the output voltage. When the input voltage exceeds the desired output voltage, the internal circuitry adjusts the pass transistor to maintain a constant 5V output. The regulator continuously monitors the output voltage and adjusts the pass transistor accordingly to compensate for any changes in the input voltage or load conditions.
