General Description
The LM136-2.5/LM236-2.5 and LM336-2.5 integrated circuits
are precision 2.5V shunt regulator diodes. These monolithic
IC voltage references operate as a low-temperature-coeffi-
cient 2.5V zener with 0.2Ω dynamic impedance. A third ter-
minal on the LM136-2.5 allows the reference voltage and
temperature coefficient to be trimmed easily.
The LM136-2.5 series is useful as a precision 2.5V low volt-
age reference for digital voltmeters, power supplies or op amp
circuitry. The 2.5V make it convenient to obtain a stable ref-
erence from 5V logic supplies. Further, since the LM136-2.5
operates as a shunt regulator, it can be used as either a pos-
itive or negative voltage reference.
The LM136-2.5 is rated for operation over −55°C to +125°C
while the LM236-2.5 is rated over a −25°C to +85°C temper-
ature range.
