MAXIM INTEGRATED / ANALOG DEVICES LM4040BIX325T Precision Voltage Reference

The LM4040BIX3-2.5+T is a precision micropower shunt voltage reference in a 3-pin SC-70 package. It provides a fixed reverse breakdown voltage of 2.5V, making it suitable for space-critical applications. Features include laser-trimmed resistors for initial accuracy of 0.2%, a temperature coefficient of ±20ppm/°C at 10mA, and a minimum shunt current of 45μA. The device offers low dynamic impedance, ensuring stable voltage regulation across a wide temperature and current range. It does not require external stabilizing capacitor for stable operation with capacitive loads. Operating over temperatures from -40°C to 85°C, it maintains low output noise of 35μVrms (10Hz to 10kHz at 100μA). Additional specifications include a reverse breakdown voltage tolerance of ±4mV and a reverse dynamic impedance of 0.3 ohms at 1mA. It is ideal for power management, consumer electronics, portable devices, and industrial applications.
