• SG7815AK-DESC Voltage Regulators - Linear Application field and Working Principle



• Introduction

The SG7815AK-DESC voltage regulator is a Linear Voltage Regulator, a type of switching power supply IC module that is designed to maintain a constant voltage when connected to a power supply output. With its low P-Qimax current, it can be used as a power transistor for low power devices. It is widely used for power management and regulating power input/output in consumer electronics, handheld devices or embedded applications.

• Application Field

The SG7815AK-DESC is a dual output voltage regulator, therefore it can be used in various applications. It can be used as an automotive regulator in engine control units, audio amplifiers, high current household consumer device such as television sets, microwave ovens, computer systems, set-top boxes, portable consumer appliances, and more.

• Working Principle

The SG7815AK-DESC voltage regulator uses a linear voltage regulation technology. This type of regulation works by using a negative feedback loop to adjust the output voltage, so that when the input voltage changes, the output voltage will remain constant.The operating principle of the SG7815AK-DESC is relatively simple. The input voltage is monitored by a voltage divider, and is then compared to a reference voltage provided by the Vout pin. The output voltage is adjusted by an error signal, through a voltage divider, to the input of an error amplifier. The voltage regulator then uses a series of pass transistors and emitter-followers to reduce the input voltage and adjust the output voltage accordingly.

• Conclusion

The SG7815AK-DESC is a linear voltage regulator that is widely used in various consumer electronics, automotive and other embedded applications. It uses linear voltage regulation to adjust the output voltage, so that when the input voltage changes, the output voltage will remain constant.
