shunt regulators with guaranteed thermal stability over a
full operation range. These monolithic ICs voltage reference
These devices exhibit a wide operating current range of 1.0 to
100mA with a typical dynamic impedance of 0.15 to 0.22Ω. The
characteristics of these references make them excellent
replacements for Zener diodes in many applications such as
digital voltmeters, power supplies and op amp circuitry
The 2.5V reference makes it convenient to obtain a stable
reference from 5.0V logic supplies, and since the LM431 series
operates as a shunt regulator, it can be used as either a positive or
negative voltage reference.
