The KA431LZTA is a three-terminal adjustable shunt regulator that offers very high accuracy. This voltage reference device is usually used to regulate the output voltage of linear or switching regulators in both general and power management applications, such as notebook computers, desktop PCs and telecom system. The KA431LZTA has a typical accuracy of 0.1%. It is designed to operate over-temperature ranges of – 40 to125 °C.

The KA431LZTA is an adjustable regulator set by two external resistors. It features an internal source-follower output stage that eliminates errors caused by loading variations. The internal pass transistor ensures low-temperature coefficient of ±15 ppm/°C (max) while the external resistors are used to set the voltage. The output voltage is set to (1.24 V) (1 + R1/R2), making the regulator ideal for applications that require an adjustable output.

The KA431LZTA voltage reference is a three-terminal device that can be used in both linear and switching power supplies. It provides excellent line and load regulation, low dropout voltage, low ripple and low temperature coefficient. The output voltage is determined by the ratio of two external resistors, R1 and R2. The output voltage can be easily adjusted by selecting proper R1/R2 ratios. The maximum output current of the KA431LZTA is 500 mA, making it a suitable choice for high-current supplies.

The KA431LZTA voltage reference can also be used in multiple applications. It can be used to set the output voltage of switching regulators, stabilizers and PFC controllers. It is also suitable for battery-powered and internet-based systems. The KA431LZTA is flexible and easy to use. It offers very accurate output, high reliability and enables efficient operation in various conditions.

The KA431LZTA voltage reference is a reliable component, offering excellent performance and stability over wide temperatures ranges. It features low power consumption and excellent noise reduction, making it an outstanding choice for power management applications. Furthermore, the KA431LZTA is a cost-competitive component and easy to use, making it an ideal choice for system designers.
