DESCRIPTION
The CLM4040 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 2.5V for
input currents between 60µA to 20mA and is an excellent
choice for battery operated applications. Avail able in three
tolerances, 0.5%, 1.0% and 2.0% and in three package
outlines, SOT-23, SO- 8 and TO - 92 .
