As a shunt reference, it operates like a precision Zener diode — it regulates the voltage across its terminals by shunting current through the cathode. The minimum cathode current is 80 µA, which sets the quiescent power floor, and it can sink up to 12 mA of output current while maintaining regulation. ## Temperature range and noise — industrial and automotive fit The 150 ppm/°C temperature coefficient means the output drifts about 0.18 mV over the full range — acceptable for 12-bit systems but worth derating for 16-bit designs. That is quiet enough for most precision analog front-ends; if your ADC reference input needs sub-10 µV noise, you would step to a lower-noise bandgap reference. ## SOT-23-3 package — footprint and rework Housed in a standard SOT-23-3 (TO-236-3 / SC-59 compatible) surface-mount package, the LM4041D12QDBZR shares the same footprint as countless small-signal diodes and references. Reflow profile follows standard lead-free solder curves; hand-soldering with a fine-tip iron is feasible for prototypes or rework.","metaTitle":"LM4041D12QDBZR Shunt Voltage Reference, 1.225V Fixed, ±1%","metaDescription":"Texas Instruments LM4041D12QDBZR precision shunt reference.
