2.5V REFERENCE DIODE
General Description
The LM136-2.5 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 Ohms dynamic impedance. A third terminal on ther LM136-2.5 allows the reference
voltage and temperature coefficient to be trimmed easily.
The LM136-2.5 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 LM136-2.5 operates as a shunt
regulator, it can be used as either a positive or negative voltage reference.

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is functional, but do not
guaranteed specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade
when the device is not operated under the listed test conditions.
The maximum power dissipation must be derated at elevated temperatures and is
dictated by Tjmax (maximum junction temperature), ThetaJA (package junction to
ambient thermal resistance), and TA (ambient temperature). The maxium allowable power
dissipation at any temperature is Pdmax = (Tjmax - TA) /ThetaJA or the number given
in the Absolute Maximum Ratings, whichever is lower.
