It delivers up to 100 mA of cathode current and sinks a minimum of 1 mA for regulation. The ±2.2% tolerance covers the commercial temperature range of 0°C to 70°C. The TO-92-3 through-hole package suits hand-assembly, prototyping, and retrofit work on existing PCBs. ## Active lifecycle and ordering the right packaging variant The LM431ACZ/LFT3 carries an Active lifecycle status and is ROHS3 compliant. The suffix denotes Tape & Box (TB) and Cut Tape (CT) packaging options — the TB variant ships in a box of loose parts on a tape carrier, while CT is a cut section of tape for small quantities. For a BOM line that needs through-hole placement, the TB box is the production pick; the CT cut tape is the prototype or rework choice. Both are the same die and same TO-92-3 package.","metaTitle":"LM431ACZ/LFT3 Shunt Voltage Reference, Adjustable, TO-92-3","metaDescription":"LM431ACZ/LFT3 adjustable shunt reference, ±2.2% tolerance, 100 mA output, 0°C to 70°C, TO-92-3.
