The CLM4041 is a two terminal precision voltage reference
with thermal stability guaranteed over temperature, a typical
dynamic impedance of 0.25Ω and very sharp turn-on
characteristics. The device has a fixed output of 1.225V for
input currents between 60µA to 20mA and is an excellent
choice for battery operated applications. Available in three
tolerances, 0.5%, 1.0% and 2.0% and in three package
outlines, SOT-23, SO-8 and TO-92.
