LM4040 Shunt Voltage Reference

Description :

The LM4040 series of shunt voltage references are versatile, easy-to-use references that cater to a vast array of applications.
The 2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures.

The LM4040 uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances, ranging from 0.1% (max) for the A grade to 1% (max) for the D grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications.

Packaged in space-saving SC-70 and SOT-23-3 packages and requiring a minimum current of 45 μA (typ), the LM4040 also is ideal for portable applications. The LM4040xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The LM4040xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.


1. Small SOT-23 Package
2. No Output Capacitor Required
3. Tolerates Capacitive Loads
4. Fixed Reverse-Breakdown Voltages of 1.225V, 2.500V, 4.096V, and 5.000V
5. Adjustable Reverse-Breakdown Version
