The LM4040AEM3-5.0+T is a precision 5.0V voltage reference from Texas Instruments, originally by National Semiconductor, housed in a SOT-23-3 package. It features ±0.1% initial accuracy, a typical temperature coefficient of 100 ppm/°C, and operates within a temperature range of -40°C to +85°C. With a typical current consumption of 68 µA and the ability to sink up to 15 mA, it offers excellent long-term stability. The “+T” indicates tape and reel packaging for automated assembly. This voltage reference is ideal for precision power supplies, data acquisition systems, and test equipment.
