Applications

The primary application of S-1212B70-M5T1U is to help power devices that need a reliable and steady power supply. It has a wide input voltage range of 4.5V to 17V and provides a regulated output voltage of 1V to 12V. It has a high power density of up to 70W/in3, making it suitable for applications in which space is limited. The S-1212B70-M5T1U is well-suited for industrial, medical, and automotive applications due to its rugged design, wide temperature range, and high efficiency.

In addition, the S-1212B70-M5T1U can provide up to eight multiple output voltage rails and is capable of controlling the outputs independently. This makes it ideal for applications that require different outputs for various components or subsystems. For example, it can be used to power a microprocessor and its associated peripherals, or to provide regulated voltage and current for high power LEDs.

Working Principle

The S-1212B70-M5T1U is a linear voltage regulator that functions by feeding a respective voltage back to the input. The regulator circuit internally compensates for input variations and then produces a steady output voltage that is independent of load current. The capability of providing multiple output voltage rails is achieved by having separate internal circuits, each responsible for controlling one output.

By allowing the regulator to keep the output voltage set within specified limits, it can maintain the best performance of the devices that are attached to it. A feature of S-1212B70-M5T1U is its current limit capability, which prevents excessive currents from being drawn in the event of a short circuit. This protects the devices attached to it from damage that could occur due to over-current.

The S-1212B70-M5T1U also has a thermal protection feature, which shuts down all outputs if the device reaches a predetermined temperature. This prevents damage to both the regulator and the attached devices, as well as to the user, in the event of an over-heating condition.

Conclusion

The S-1212B70-M5T1U is a linear voltage regulator that is well-suited for industrial, medical, and automotive applications due to its rugged design, wide temperature range, and high efficiency. It can provide up to eight multiple output voltage rails and is capable of controlling the outputs independently. In addition, its current limit and thermal protection features protect the regulator and devices attached to it from damage in case of short circuit or over-heating.
