Overview
The TL431AICT is an adjustable shunt voltage reference from STMicroelectronics, part of the TL431 series. It provides a reference voltage range from 2.495V to 36V with an initial accuracy of ±1%. The device operates within a current range of 1mA to 100mA and features a typical dynamic impedance of 0.22 Ohm. It is housed in a surface-mount SOT-323-6 package and supports an operating temperature range from -40°C to +125°C.
Feature Summary
- Adjustable output voltage capability between 2.5V and 36V using two external resistors
- High precision with guaranteed temperature stability across the full operating range
- Wide cathode current operation from 1mA to 100mA for flexible circuit design
Applications
- Precision voltage regulation in power supply circuits
- Programmable linear regulators
- Comparator references in control systems
Procurement Notes
Verify the specific suffix 'ICT' against the official STMicroelectronics datasheet to confirm the SOT-323-6 package and ±1% tolerance grade. Ensure the selected variant meets the required thermal and electrical specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when a compact surface-mount solution is required for adjustable voltage referencing. The SOT-323-6 package offers space efficiency, while the wide operating temperature range suits demanding industrial or automotive environments requiring stable reference performance.
Part Context
This component belongs to the TL431 family of programmable shunt voltage references. These devices are widely used as low-cost alternatives to Zener diodes, offering superior performance in terms of temperature coefficient and dynamic impedance for precision analog and power management applications.
Replacement Considerations
Compatible substitutes include other manufacturers' TL431 variants with matching SOT-323-6 packaging and ±1% accuracy. Verify pinout compatibility and thermal characteristics when transitioning to alternative sources.
