The shunt can sink up to 15 mA while maintaining regulation; the minimum cathode current is 110 µA. Design the bias resistor to keep the shunt current within this range across the full input voltage swing and load variation — too little current and the reference drops out of regulation, too much and the part exceeds its power dissipation in the SOT-23-3.
Texas Instruments has not published an official successor for the LM4040DIM3X-10. For a drop-in pin-compatible alternative within the LM4040 family, consider the LM4040AIM3-10 — it offers the same 10 V output and SOT-23-3 footprint but with a tighter ±0.1% tolerance. Verify the tolerance grade and tempco against your BOM requirements before substituting.
