SG7815K Application Field and Working Principle

The SG7815K is a voltage stabilizing circuit that is classified as a linear voltage regulator. It is designed to provide consistent levels of output voltage , usually lower than of the input voltage, and convert variable levels of DC current into a more stable voltage for a particular electronic device. This device is used to protect electronic components from possible damages caused by spikes in voltage, enable efficient load sharing between output channels, and maintain the exact same voltage level from different sources.

Application Fields

The SG7815K\'s primary application fields are found in automotive, industrial, and consumer electronics, such as medical engineers, automobiles, inverters, automation and control systems, and communication network systems. It is also often used in the home due to the immense number of electrical and electronic appliances which require consistent and stable levels of voltage in order to operate without possible damage to the internal components.

Working Principle

The SG7815K is a linear voltage regulator that operates on the principle of Voltage Drop (VD) principle. In this system, a power overload is changed from an AC voltage to a DC voltage and then is regulated using a range of resistors to a consistent level of output voltage. The SG7815K is designed to protect electronic components from damage that can occur from input voltage noise, surges, and over voltages.The voltage regulator contains three main components: the zener diode, the series resistor, and the linear regulator integrated circuit. The zener diode is used to clamp the voltage at a particular point and regulate it below the desired voltage output level. The series resistor is used to control the current flow while the linear regulator IC is used to convert DC current into a more stable voltage output.The device is usually connected to the power source by a selector switch or circuit breaker. When the power switch is turned on, the SG7815K will begin operating and the output voltage will scale in a linear fashion according to the inputs provided. In order to ensure that the output voltage is maintained, the input voltage must remain high enough to overcome the output voltage drop.

Conclusion

The SG7815K linear voltage regulator is a practical solution for electronic equipment and devices which require consistent and reliable operation in order to not suffer damage over time. The device can be used in a variety of applications including those found in automotive, industrial, and consumer products due to the selectable input voltage range and the ample output current it can provide. The device\'s working principle makes use of resistors, a zener diode, and a linear regulator IC to convert varying input DC voltages into a stable, low voltage output to protect the internal components of the application.
