DESCRIPTION

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.
