S-1155B25-U5T1U is a linear voltage regulator designed for applications requiring precise and stable voltage sources, such as voltage regulation of an electronics system. The S-1155B25-U5T1U is an industry-standard three-terminal linear regulator. It offers an output voltage range of 0.7V to 25V and current output limits up to 800mA.

Application Field

The S-1155B25-U5T1U is suitable for a wide range of general-purpose voltage regulation applications such as computer systems, telecommunications equipment, instrumentation, and other electronic equipment. It can also be used in automotive applications, including car radios and dashboard or dashboard instruments. It provides a low-ripple operation of up to ±2% from 0°C to 70°C.

Working Principle

The S-1155B25-U5T1U does not use feedback like some of the other linear voltage regulators, instead, its working principle is based on an internal reference voltage that is set to 0.7V to 25V and three terminals. When the regulator is used, the output voltage remains very close to the reference voltage when the load is within the regulator’s specified operating current range.

The S-1155B25-U5T1U employs a protected bandgap reference that ensures stability over a wide range of temperatures, as well as a protected output transistor which allows the use of very large output currents, up to 800mA. It also features a short-circuit protection, which will quickly shut down the output in the event of a short-circuit.

The adjustability of the S-1155B25-U5T1U linear voltage regulator can be set by just two pins: the adjustment pin and the reference pin. The adjustment pin is used to adjust the output voltage. The reference pin, when powered, sets the reference voltage to the desired value. This results in an output voltage that remains stable.

In addition, the S-1155B25-U5T1U offers thermal shut-down protection. If the operating temperature is too high, the temperature-sensitive shut-down circuit will automatically shut down the device, which prevents the device from being damaged by excessive heat.

In order to ensure operation at extreme temperatures, the S-1155B25-U5T1U also offers protection against reverse voltage, which protects the device from damage in the event that the output voltage spikes beyond its specified limit. This ensures reliable and long-lasting operation even in the most demanding applications.

Conclusion

The S-1155B25-U5T1U is an industry-standard three-terminal linear regulator. It offers a precision output voltage range of 0.7V to 25V, current output limits up to 800mA, and features such as thermal protection, short-circuit protection, and reverse voltage protection. Its wide range of applications makes it suitable for a variety of general-purpose voltage regulation applications, including computer systems, telecommunications equipment, instrumentation, and other electronic equipment. Additionally, its adjustable output function ensures stable and reliable operation even in extreme environmental conditions.
