Description

STMicroelectronics TL431AIZ Precision Programmable Reference

The TL431AIZ from STMicroelectronics is a versatile, precision programmable voltage reference that offers excellent stability and accuracy for a wide range of applications. This three-terminal adjustable shunt regulator comes in a TO-92 package, providing a reliable and compact solution for your voltage regulation needs. With the ability to set the output voltage with two external resistors, the TL431AIZ offers flexibility and precision in managing system voltages.

The device features a guaranteed voltage reference tolerance of ±0.5% at 25°C, and ±1% over the entire industrial temperature range of -40°C to +85°C. This tight tolerance ensures consistent performance and makes the TL431AIZ an ideal choice for high-precision applications. The output voltage can be set to any value between Vref (approximately 2.495V) and 36V, with a typical dynamic output impedance of 0.2Ω. This low output impedance and the high drive capability of up to 100mA make the TL431AIZ suitable for a variety of applications, including adjustable power supplies, switching power supplies, and battery chargers.

With a typical temperature coefficient of only 50ppm/°C, the TL431AIZ provides a stable voltage reference over a wide temperature range, ensuring reliable operation under varying environmental conditions. The device's low output noise and excellent thermal stability make it a preferred choice for precision applications such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and voltage monitoring circuits.

For ease of use, the TL431AIZ features a simple and intuitive design that allows for straightforward implementation into existing circuits. Its standard TO-92 package is widely used and well-known in the industry, making it easy to handle and solder, even for hobbyists or those with less advanced equipment.

In summary, the STMicroelectronics TL431AIZ is a highly reliable and precise adjustable shunt regulator that offers designers a cost-effective solution for obtaining a stable reference voltage. Whether used in power supplies, battery management systems, or precision voltage monitoring, the TL431AIZ is an excellent choice for maintaining voltage accuracy and stability in your electronic designs.
