LM4041xx 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 operating temperature range: - 40 to + 85 °C
-   Extended (- 40 to +125 °C) version available under request
-   100 ppm/°C maximum temperature coefficient
-   Available in SOT23-3L and SOT323-5L packages
