Applications and Working Principle of S-1167A50-M5T1G Linear Voltage Regulator

The S-1167A50-M5T1G is typically used in DC/DC converter applications, automotive under-hood electronics, and telecommunication systems. Having a maximum current rating of 1.4A, it is also well-suited for powering microprocessors, DSPs and FPGAs. The device features a wide input voltage range from 2.25V to 9V and operates at temperatures from -40°C to 125°C. The S-1167A50-M5T1G also features a wide output voltage range from 0.8V to 5.25V, and it has a ±0.9V accuracy over temperature. The device has a low quiescent current of 8mA and a high efficiency of 86 percent at 1A, which makes it an ideal choice for power-sensitive applications.The working principle of the S-1167A50-M5T1G linear voltage regulator is based on the linear regulator principle, where the output voltage is regulated by controlling the on- and off- times of an internal control transistor. When the device is enabled, the control transistor switches on and starts charging the output capacitor. When the output voltage reaches the desired level, the control transistor switches off, and the output voltage is regulated by adjusting the current to the output capacitor. This operating principle allows for fast transient response and low noise operation, making the device well-suited for use in a variety of applications.In addition, the S-1167A50-M5T1G features an integrated overtemperature protection circuit to protect against over-temperature conditions. The protection circuit prevents the output voltage from increasing above a preset temperature. This feature increases the reliability of the device in high-temperature environments. The device also features an integrated over-current protection circuit to protect the device from current overloads. The over-current protection circuit monitors the current drawn by the device and automatically shuts down the output if the current exceeds the rated limit. This feature ensures the safety of the device in event of an overload. Conclusion

The S-1167A50-M5T1G linear voltage regulator is a robust and reliable device well-suited for use in a variety of applications. It is designed to provide high efficiency and low quiescent current, making it ideal for power sensitive applications. The device has a wide input voltage range and operates at temperatures from -40 to 125° Celsius. It also features an integrated overtemperature and over-current protection circuit to increase the reliability and safety of the device in event of an overload. The S-1167A50-M5T1G is an ideal choice for powering microprocessors, DSPs and FPGAs, DC/DC converter applications and automotive electronics.
