Additional Details:

The LM4040DYM3-4.1 is a two-terminal shunt voltage reference. To use it, a resistor must be connected in series between the supply voltage and the LM4040. The resistor limits the current through the device and drops the excess voltage. It is available in a SOT-23 package. The LM4040 is ideal for applications requiring a stable and accurate voltage reference with minimal power consumption.
