Adjustable shunt reference with ±1% initial tolerance
It operates as a shunt (parallel) reference, sinking up to 100 mA through the cathode while regulating the output voltage set by two external resistors. The 600 µA minimum cathode current ensures the internal error amplifier stays biased across the full output range up to 36 V. This part is built on the industry-standard TL431 architecture, widely used in isolated power supplies, linear regulators, and precision voltage monitoring circuits.
Last Buy — plan your final order window
This means Texas Instruments has announced end-of-life for this specific variant, and there is a final purchase window before production ceases. Procurement teams should confirm the last-time-buy deadline with their distributor and secure sufficient inventory for ongoing production runs. After the LTB closes, the part will only be available through surplus or broker channels.
SOIC-8 footprint — board-level fit
The package is 8-SOIC with a 5.30 mm body width.
