Adjustable shunt reference in a small SOT-23-5 package
It delivers a programmable output from 2.495 V up to 36 V, with a ±2.2% tolerance grade suitable for general-purpose regulation in power supplies, data converters, and supervisory circuits. Rated for 100 mA continuous cathode current with a minimum bias of 1 mA, it covers the typical load range for shunt references in feedback loops and precision dividers.
For existing BOM lines, availability is limited to independent distribution and surplus inventory — quoted to order against the specific quantity required.
The TL431QDBVRE4 is supplied in a SOT-23-5 package (also designated SC-74A), with a Tape & Reel shipping medium. The small body and 0.95 mm lead pitch make it hand-solderable with a fine-tip iron; the low thermal mass means it reflows cleanly under hot air without cooking adjacent components.
