Application Field

The SC1453ISK3.3TRT is suitable for applications like motor pump motor drives and generator motor drives, industrial automation, motor control, power management, and systems requiring improved precision and current-limit protection. It is ideal for systems that require space-saving and high performance voltage regulation, precise and adjustable control of output voltage, and low ripple voltage.

Working Principle

The SC1453ISK3.3TRT is a linear regulator that controls the output voltage by comparing an external reference, or feedback voltage, to an applied voltage across a feedback network. When the voltage across the feedback network is greater than the reference voltage, the regulator output decreases. In the same manner, if the feedback voltage is lower than the reference voltage, the output voltage of the regulator increases. This regulating circuit is often combined with other circuitry for controlling additional features such as current limiting, thermal shutdown, and regulation of multiple output voltages.

The SC1453ISK3.3TRT standard features include a reference voltage precision of ±3%, an adjustable output voltage range of 0.8V to 12.6V, and a temperature coefficient accuracy of ±2.5mV/°C. The parts also incorporate safety features such as thermal shutdown, current limiting, and overvoltage protection. These features make it suitable for protection of sensitive systems and equipment against voltage spikes, voltage overshoot and other external factors.

Furthermore, the SC1453ISK3.3TRT output voltage is monitored by an external feedback circuit, which also acts as a voltage reference. This means that the reference voltage is periodically adjusted, making it possible to maintain the output voltage within a specified voltage range.

Conclusion

The SC1453ISK3.3TRT is a high-performance linear voltage regulator that can be used in a variety of system designs.
