Minimum cathode current is 1 mA, so the part stays in regulation even at light load — useful for battery-powered circuits where every microamp counts. ## SOT-323-6L — small footprint, field-swappable Surface-mount with standard lead pitch; can be hand-soldered with a fine-tip iron in a pinch, though a hot-air station is cleaner for production rework. ## RoHS status — legacy BOM consideration Marked as RoHS non-compliant — the TL1431CCT uses lead-bearing solder finish.","metaTitle":"STMicroelectronics TL1431CCT Shunt Reference, ±0.4%, 100 mA","metaDescription":"ST TL1431CCT adjustable shunt voltage reference, ±0.4% tolerance, 100 mA output, SOT-323-6L.
