The reference is rated for a cathode current range from 125 µA up to 15 mA, giving the designer flexibility to balance quiescent power against load drive capability. ## Noise and temperature drift — the precision envelope Temperature coefficient is 100 ppm/°C. The SOT-23-3 package (also listed as TO-236-3 / SC-59 / SOT-23-3) keeps the board footprint small, but the thermal dissipation is limited — the 15 mA maximum output current is rarely used at the full rating in this package without careful PCB copper area for heat sinking. RoHS compliance is assumed for the lead-free SOT-23-3 package, though the evidence does not explicitly state a RoHS certificate number.","metaTitle":"LM4040A10IDBZT 10 V Shunt Reference, ±0.1%, SOT-23-3","metaDescription":"Texas Instruments LM4040A10IDBZT precision 10 V shunt voltage reference, ±0.1% tolerance, 100 ppm/°C drift, 180 µVrms noise.
