The SC431LC5SK-2TRT is an integrated-circuit Voltage Reference which belongs to the PMIC (Power Management Integrated Circuit) family. It is a low-power, low-noise, accurate Voltage Reference, which provides stability of output voltage in all application conditions. Thus, it is widely used in all kinds of electronic applications, from test instruments and automotive to machine tools and industrial control systems.

As the reference voltage source, the SC431LC5SK-2TRT offers reliable voltage stability for precision electronics. It features a precisely trimmed internal reference voltage between 1.242V and 1.8V, and a maximum reference output current of 25mA. To operate with a wide input voltage source up to 24V, the voltage regulator accepts an input voltage range of 4V to 36V. The maximum quiescent current of the part is a low 25uA.

Due to its high accuracy reference voltage and excellent stability, the SC431LC5SK-2TRT is widely used in automotive, lighting, medical device and other applications. For instance, in cars, the SC431LC5SK-2TRT are used in the infotainment system, headlights or audio/video systems. These accessores need constant reference voltage to work properly, so a PMIC Voltage Reference is essential. The SC431LC5SK-2TRT is also used in portable medical equipment and monitoring systems.

The SC431LC5SK-2TRT work with the following functional blocks comprised of a temperature sensor, a comparator, an op-amp, Voltage Reference and a voltage regulator. The temperature sensor monitors the temperature variations and produces an output voltage to the comparator. The comparator uses the reference voltage output from the Voltage Reference and compares it to the temperature sensor output. Based on the comparison of the two, the output of the comparator is then sent to the op-amp and voltage regulator via the control line.

The op-amp amplifies the comparator output and, depending on the magnitude, adjusts the output voltage of the voltage regulator accordingly. The voltage regulator, operating with a fixed input voltage, converts the provided input voltage into the required output voltage. The output voltage is then provided to the electronic circuit or device that needs it.

The SC431LC5SK-2TRT is designed to be very efficient in operation. It has low power consumption and operates at very low noise levels. It also offers protection against under-voltage, over-voltage and short-circuit. This makes the SC431LC5SK-2TRT suitable for use in a wide range of applications.

Overall, the SC431LC5SK-2TRT is a reliable and low-noise Voltage Reference suitable for all kinds of applications, from automotive and lighting to medical devices and industrial control systems. It provides an accurate reference voltage for precise control of electronics and operates with the utmost efficiency. Its features make it an ideal solution for various applications.
