LM4040 Shunt Voltage Reference is very stable over different conditions


STMicroelectronics’ LM4040 is low power and high accuracy shunt voltage reference providing a stable output voltage over the industrial temperature range (-40°C to +125°C), with a maximum temperature coefficient of 70 ppm/°C. It is available in 0.1%, 0.2%, 0.5%, and 1% initial accuracy versions. The SOT323- 5L and SOT23-3L packages can be designed in applications where saving space is a critical issue. The very low operating current is a key advantage for power restricted designs. The LM4040 is very stable and can be used in a broad range of application conditions.


  • Fixed 2.048 V, 2.5 V, 3.0 V, 4.096 V, and 5.0 V output voltages
  • Ultra-low operating current: 10 µA at +25°C
  • High precision at +25°C: ±0.1% (LM4040A), ±0.2% (LM4040B), ±0.5 % (LM4040C), ±1% (LM4040D)
  • Very low LF noise: typ. 10 µ VP-P
  • Stable when used with capacitive loads
  • Industrial (-40°C to +125°C) temperature range
  • 70 ppm/°C max. temperature coefficient
  • Available in SOT23-3L and SOT323-5L packages
