The LM4040-N series from Texas Instruments is a precision micropower shunt voltage reference designed for space-critical applications. This specific part, the LM4040CEM3X-5.0/NOPB, provides a fixed reverse breakdown voltage of 5V.
Key electrical specifications include an output voltage tolerance of ±0.1% at 25°C and a low temperature coefficient of 100ppm/°C maximum. It operates over a wide current range from 60µA to 15mA and exhibits low output noise of 35µVrms from 10Hz to 10kHz. The device tolerates capacitive loads and does not require an external output capacitor.
Packaged in a small SOT-23 (DBZ) surface-mount package with 3 pins, this component is suitable for designs where board space is limited. It operates within an industrial temperature range of -40°C to +85°C, with an extended range available up to +125°C.
