The device features an adjustable output, thermal shutdown protection, fold back current limiting and programmable output current limiting.

Application Fields

The S-1172B32-U5T1U is a versatile device, and can be used for a variety of different applications. It is especially well-suited for applications in the industrial, medical, and automotive industries. In these areas, the device can be used to regulate voltage and provide a stable output across a wide range of input voltages. It is also useful in battery-powered applications, where it can be used to maintain the output voltage and current when the battery voltage decreases. Additionally, it can be used in telecommunication, networking and consumer electronic applications.

Working Principle

The S-1172B32-U5T1U is a linear voltage regulator. This means that it employs the technique of regulating the voltage by applying a voltage drop across itself. The device consists of a series of transistors that act like a current limiting element as well as a voltage divider. When the output voltage needs to be regulated, the transistor limits the current, while providing the same voltage drop across itself. This voltage drop is then used to regulate the output voltage.

The device can be set up in either the adjustable or fixed output mode. In the adjustable output mode, the transistor limits the current and sets the voltage based on a preset voltage. This voltage can be adjusted to provide the desired output voltage. In the fixed output mode, the transistor is used to limit the current, while the output voltage is determined by the voltage divider.

In order to protect the device from over-currents, it is equipped with a fold back current limiting feature. This feature limits the output current when it reaches a predetermined level, and prevents the device from being damaged. Additionally, the device can also be configured with a programmable output current limiting feature, which allows the amount of current that can be applied to the output voltage to be limited.

Conclusion

The S-1172B32-U5T1U is a powerful and versatile linear voltage regulator developed by Sanken. It is capable of providing reliable power regulation and stability in a range of different applications in the industrial, medical and automotive industries, as well as in battery-powered applications. The device also features adjustable, fold back current limiting, and programmable output current limiting. With its high level of performance and reliability, it is no wonder why this device has become so popular in these sectors.
