KA723D Application Field and Working Principle

The KA723D is a linear voltage regulator with a 2A output current capacity and 3A peak load current. It is a positive-voltage regulator with an adjustable output voltage of range from 0V to 35V. KA723D has various features such as over-temperature protection, adjustable voltage output, thermal shut-down, over-current protection, and soft start. The KA723D could be powered by a 0 - 24V input supply.KA723D is widely applied in the fields of industrial control and automotive applications. Its adjustable output voltage makes KA723D suitable for a wide range of devices, like DC motor driving, battery charging, and LED driver. In addition, KA723D is made with a less complex structure and is cost-effective, thus providing a perfect solution to many control related applications.Working PrincipleThe operating principle of the KA723D is based on the "linear regulator" architecture. It has two main components, a voltage regulator and an error amplifier. The voltage regulator is used to control the output voltage while the error amplifier is utilized to regulate the output voltage level.The voltage regulator always keeps the output voltage equal to or the set voltage. For example, if the output voltage is set to 5V, the regulator will apply the resistance to the load to maintain the output voltage at 5V. In addition, the error amplifier is used to compare the actual output voltage to the set voltage and produces an error signal that drives the regulator to maintain the output level.The combination of both devices is what makes the KA723D an efficient voltage regulator. With the help of the comparative output voltage feedback loop and current limiting features, KA723D is able to not only provide precise and stable output but also to cope with overload situations.To sum up, KA723D is a linear voltage regulator capable of delivering an adjustable voltage range from 0V to 35V and up to 2A continuous or 3A peak output current. It has a simple structure and is cost-effective, which makes it suitable for various control related applications such as DC motor driving, battery charging, and LED driver. In addition, it is equipped with several protection features, making it a reliable choice for industrial control and automotive applications.
