Housed in a SOT-23-5 package, it draws 100 µA quiescent supply current and can source up to 20 mA to the load. The 75 ppm/°C temperature coefficient keeps the output stable across the full -40°C to 125°C junction temperature range, making it suitable for industrial sensor interfaces, automotive ECU references, and precision ADC/DAC bias circuits where board space is tight. ## Active, ROHS3, and available in tape and reel The LM4128AMF-3.0/NOPB carries an active lifecycle status and is ROHS3 compliant. The NOPB suffix confirms lead-free (RoHS) construction. Packaging options include Tape & Reel (TR) and Cut Tape (CT), which covers both volume production reels and prototype or small-batch quantities.","metaTitle":"LM4128AMF-3.0/NOPB Voltage Reference, ±0.1% Tolerance","metaDescription":"TI LM4128AMF-3.0/NOPB series voltage reference, fixed 3V output, ±0.1% tolerance, 75 ppm/°C drift, 20 mA output, SOT-23-5.
