MAXIM INTEGRATED / ANALOG DEVICES LM4040BIM325T Micropower Voltage Reference

The LM4040BIM3-2.5+T is a precision micropower shunt voltage reference housed in a compact 3-pin SOT-23 package, ideal for space-constrained applications. It offers a 0.2% initial accuracy with a ±20ppm/°C temperature coefficient at 10mA. The device operates with a minimum shunt current of 45μA, features low dynamic impedance, and maintains a stable 2.5V breakdown voltage across -40°C to 85°C. It does not need an external capacitor for stable operation, produces low output noise of 35μVrms (10Hz to 10kHz), and guarantees voltage tolerance within ±4mV, making it suitable for portable and industrial electronic systems.
