Overview
The LM4041BILT-1.2, produced by STMicroelectronics, is a micropower shunt voltage reference. It provides a stable 1.225 V output voltage with an initial accuracy of 0.1% at 25 °C and a low temperature coefficient. This component is available in SOT23-3L surface mount packages, making it ideal for applications where space saving is critical. The low operating current of 40 µA at 25 °C is a significant advantage for power-restricted designs. The LM4041 is highly stable and can be used in a broad range of application conditions.
