Working Principle of NCV612SQ27T1G

The NCV612SQ27T1G uses a linear voltage regulator technology, which receives an input voltage higher than its output voltage and reduces it to a desired voltage level. This device is internally constructed of two NPN transistors working together to create a simple and efficient regulator. The input voltage is applied to the base of the series transistor, which in turn applies a current to the emitter of the series transistor and collector of the shunt transistor through the resistive element, or the series inductor. When the voltage at the emitter of the series transistor is greater than the setpoint voltage at the reference input, the shunt transistor turns on and increases the electrical resistance through it, consequently regulating the output voltage of the device. This process is repeated multiple times every second, and therefore creates a smooth output voltage.
