Housed in a SOT-23-3 package, it is a surface-mount part suited for ADC biasing, comparator thresholds, and power-supply monitoring in industrial and automotive temperature environments spanning -40°C to 125°C. ## What the ratings mean for the BOM The shunt architecture draws a cathode current of 65 µA typical, and the part can source up to 15 mA to the load. That 65 µA quiescent is the minimum bias current needed to keep the reference in regulation — budget it in the supply rail alongside the load current. For battery-powered designs, the 65 µA floor is low enough to leave the reference on continuously without draining the cell overnight. ## Package and rework notes The SOT-23-3 package (TO-236 / SC-59 equivalent) is a three-pin body. It reflows cleanly with a standard hot-air profile — no hidden thermal pad, no risk of tombstoning if the paste stencil is right. ## Lifecycle and sourcing This part carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"LM4050CEM3-2.1+T Shunt Voltage Reference","metaDescription":"Maxim LM4050CEM3-2.1+T precision shunt reference: 2.048V output, ±0.5% tolerance, 50ppm/°C drift, SOT-23-3.
