Precision micropower shunt voltage reference

The LM4041 is a micropower shunt voltage reference, providing a stable 1.225 V output voltage, with an initial accuracy of 0.1% @ 25 °C and a low temperature coefficient. Available in SOT323-5L and SOT23-3L surface mount packages, it can be designed in applications where space saving is a critical issue. The low operating current is a key advantage for power restricted designs. In addition, the LM4041 is very stable and can be used in a broad range of application conditions.

Key Features

  • Fixed 1.225 V typical output voltage
  • Ultra low operating current: 40 μA at 25 °C
  • High precision: +/- 0.1% @ 25 °C (0.2%, 0.5% and 1% versions are also available)
  • Stable when used with capacitive loads
  • Industrial (- 40 to+ 85 °C) and Extended (- 40 to +125 °C) temperature range versions available
  • 100 ppm/°C maximum temperature coefficient
  • Available in SOT23-3L and SOT323-5L packages
