Working Principle

The SG7815AK Linear Voltage Regulator uses a feedback system to control the output voltage. It takes the input voltage as an input source and applies a switching controller to adjust the output voltage accordingly. The feedback system compares the output voltage to the reference voltage and adjusts the output voltage continuously.The voltage regulator has a switching circuit, which consists of a transistor, a diode, and a reference voltage. The transistor and the diode combine to form a voltage multiplier, which steps up the input voltage to provide a higher output voltage. The reference voltage is also used to compare the output voltage to the desired output value and adjusts the amount of current delivered to the output accordingly.

Conclusion

The SG7815AK Linear Voltage Regulator is a reliable and cost-effective solution for a wide range of applications, including mobile power systems, portable electronic devices, and power consuming applications such as energy meters, temperature controllers, and audio amplifiers. It has a wide input voltage range of 2V-18V, an output voltage range of 1.5V-17V, and a high power efficiency of 85%. The device also has a switching circuitry that steps up the input voltage, a feedback system to adjust the output voltage, and short circuit protection.
