KA431SLMFTF Integrated Circuits (ICs)

PMIC – Voltage Reference is a crucial component in today’s electronic designs. The KA431SLMFTF is an adjustable precision shunt voltage reference designed to provide an accurate and low cost reference voltage source. It offers excellent line and load regulation, low temperature drift, and tight voltage accuracy over a wide temperature range.

The KA431SLMFTF has two wide operational ranges, either 0.2V to 36V or 44V to 66V and can provide an output voltage range of 0V to 36V. It features an adjustable two-terminal output shunt regulator with a tight voltage accuracy of 2% over a wide temperature. The KA431SLMFTF has a wide range of applications, where the designers require an accurate reference voltage in a wide range of applications.

The working principle of the KA431SLMFTF is quite simple. It uses a two-terminal output shunt regulator to provide an adjustable reference voltage for the system. The two terminals consist of a lower voltage range terminal and an upper voltage range terminal. The upper terminal is connected to the reference voltage, and the lower terminal is connected to the external ground. The output voltage is determined by adjusting the output current of the external current setting resistor which is connected to the reference voltage. As the voltage across the resistor increases, the output voltage increases accordingly.

The KA431SLMFTF is mainly used in voltage-sensitive systems like LCD televisions, components in consumer and industrial electronics and digital control systems. It has wide applications in the consumer electronics industry, such as in LED based televisions, digital cameras, DVD players, optical drives and DVD recorders. It is used in commercial and industrial sectors as well, such as in digital controllers, metering systems, industrial robots, test and measurement equipment and photoelectric equipment. Furthermore, it is also used in automotive electronics, where it is used to control the injection system, engine speed control and transmission speed control.

In conclusion, the KA431SLMFTF is an excellent choice for wide range of applications in consumer, commercial, industrial and automotive electronics. It is an adjustable precision shunt voltage reference that provides an accurate and low-cost reference voltage source with excellent line and load regulation, low temperature drift and tight voltage accuracy across a wide temperature range.
