The LM336Z-2.5 integrated circuit is a precision 2.5V shunt regulator diode. This monolithic IC voltage reference operates as a low-temperature-coefficient 2.5V zener with 0.2 Ohm dynamic impedance. A third terminal on the LM336Z-2.5 allows the reference voltage and temperature coefficient to be trimmed easily.
It is useful as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 2.5V makes it convenient to obtain a stable reference from 5V logic supplies. Further, since the LM336-2.5 operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
