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.
