LM4041 Precision micropower shunt voltage reference Datasheet - production data Description 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 SOT323-5L SOT23-3L 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 Features application conditions. Fixed 1.225 V typical output voltage Ultra low operating current: 40 A 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 Applications Computers Battery chargers Switch mode power supply Battery operated equipment Data acquisition systems Energy management Instrumentation February 2014 DocID018817 Rev 4 1/16 This is information on a product in full production. www.st.comContents LM4041 Contents 1 Pin configuration 3 2 Maximum ratings 4 3 Electrical characteristics . 5 4 Typical performance characteristics 6 5 Package mechanical data . 8 6 Packaging mechanical data 12 7 Order codes . 14 8 Revision history . 15 2/16 DocID018817 Rev 4
