LM4040 Precision Micropower Voltage References

Texas Instruments LM4040 Precision Micropower Shunt Voltage References are versatile, easy-to-use devices for many applications. The 2-pin fixed-output LM4040 needs no external capacitors and is stable with all capacitive loads. Furthermore, the references deliver low dynamic impedance, noise, and temperature coefficients to support a stable output voltage over a wide range of operating currents and temperatures.
