±0.5% tolerance — the accuracy anchor for your reference rail
The adjustable output spans from a 1.233 V minimum up to 10 V, set by two external resistors.
12 mA output, 80 µA cathode — sizing the bias resistor
Rated for 12 mA maximum output current, this shunt reference can sink enough current to bias a string of comparators or an ADC reference input.
SOT-23-3 — board-area fit and thermal limits
Housed in a SOT-23-3 package (also listed as TO-236-3 / SC-59), the part occupies minimal board area. The small footprint suits dense mixed-signal layouts, but the junction-to-ambient thermal resistance limits power dissipation; at 12 mA output and 10 V drop the die runs hot, so derate the output current or add copper pour on the cathode trace.
