Furthermore, its wide input voltage range, stability across temperature variations, and built-in EMC protection make it an ideal choice for industrial, automation and renewable energy applications.

Working Principle

The S-1167B20-M5T1G works on the principles of linear voltage regulation. It uses a fixed linear reference voltage to regulate the output voltage. This reference voltage is provided by an internal voltage reference circuit, which stabilizes the output voltage over temperature and line variations.

The S-1167B20-M5T1G features a low dropout voltage performance, which allows it to maintain the same output voltage even with a small difference between the input and output voltages. The current limit is controlled by an internal current sense amplifier, which provides additional protection against over-currents.

The S-1167B20-M5T1G also provides thermal protection, which prevents the device from overheating. Over-Temperature Protection (OTP) is a feature of the S-1167B20-M5T1G, which is triggered when the device temperature exceeds its thermal limit. The OTP circuit will shut off the voltage regulator to protect the device from damage.

The S-1167B20-M5T1G features a wide input voltage range of 3.1V to 15V, making it suitable for applications with varying voltage input requirements. The device also offers high output accuracy, providing a voltage accuracy of ±1%. It also offers an EMI filter, improving the output noise performance.

Conclusion

The S-1167B20-M5T1G is a versatile and efficient linear voltage regulator. Its low dropout voltage performance and constant voltage output make it suitable for a variety of applications, from home entertainment systems to medical equipment. Its wide input voltage range, thermal protection, and EMI filter make it an ideal solution for industrial, automation and renewable energy applications. It is also suitable for use in multichannel controllers, emergency backup systems and AC/DC power converters.
