SG7815T-883B Application Field and Working Principle
SG7815T-883B is a linear voltage regulator from the Power Management IC (PMIC) family. A linear regulator is commonly used in power management since it provides the output voltage in a single-stage design, with minimal input-output voltage differential and low noise. In this sense, SG7815T-883B is specifically designed for low-dropout (LDO) switching power supplies and has built-in features to improve reliability and provide advanced protection against failure.
Features and Benefits of SG7815T-883B
- Low quiescent current: the quiescent current of SG7815T-883B is very low, which can significantly reduce power consumption.
- High ripple rejection: SG7815T-883B has high output voltage ripple rejection which ensures the integrity of the output voltage.
- Over-voltage protection: SG7815T-883B also provides over-voltage protection, which can help to reduce the risk of failure due to excessive input voltage.
Applications of SG7815T-883B
SG7815T-883B is widely used in various electronic systems where stable voltage is required, such as cellular phones, PDAs, digital cameras, notebook computers and other portable electronic devices. In these applications, SG7815T-883B provides stable and reliable power management, helping to ensure the longevity and performance of the products. Additionally, SG7815T-883B can be used in RF power amplifier applications to provide stable voltage.
Working Principle of SG7815T-883B
SG7815T-883B is an integrated voltage regulating system which consists of two parts: an internal amplifier and external components. The internal amplifier is a low-power, low-noise operational amplifier and its purpose is to sense and compare the input and reference voltage. The external components work with the internal amplifier to form a feedback loop. The voltage difference between the input and the reference voltage is constantly monitored by the internal amplifier to keep the output voltage constant.
SG7815T-883B operates in two distinct modes. The linear regulation mode senses the voltage variance between the input and the reference voltage, and it adjusts the output current accordingly. The second mode is the on-off mode, where the voltage is regulated by switching the outputs on or off as required. In this mode, the voltage is adjusted by changing the duty cycle of the output pulses.
In addition, SG7815T-883B is designed to provide additional protection against failure. It has built-in protection against short circuits, over-temperature and over-current. This can help protect the product from any potential damage due to unexpected current or temperature spikes.
Conclusion
The SG7815T-883B linear voltage regulator from the Power Management IC (PMIC) family is specifically designed for low-dropout (LDO) switching power supplies. It has many advantages over conventional linear regulators, most notably low quiescent current, excellent ripple rejection and advanced protection against failure. SG7815T-883B is commonly used for various electronic systems where stable voltage is critical and can also be used in RF amplifier applications.
