LM136A-2.5/LM136-2.5QML
Reference Diode
General Description
The LM136A-2.5/LM136-2.5 integrated circuit is a precision
2.5V shunt regulator diode. This monolithic IC voltage refer-
ence operates as a low-temperature-coefficient 2.5V zener
with 0.2Ω dynamic impedance. A third terminal on the
LM136-2.5 allows the reference voltage and temperature co-
efficient to be trimmed easily.
The LM136-2.5 is useful as a precision 2.5V low voltage ref-
erence for digital voltmeters, power supplies or op amp cir-
cuitry. The 2.5V make 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.

Note 1: 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 guarantee 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.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package
junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/
θ
JA or the number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 1.5KΩ in series with 100pF.
Note 4: Parameter tested go-no-go only.
Note 5: Pre and post irradiation limits are identical to those listed under DC electrical characteristics. These parts may be dose rate sensitive in a space
environment and may demonstrate enhanced low dose rate effect. Radiation end point limits for the noted parameters are guaranteed only for the conditions as
specified in Mil-Std-883, Method 1019.
Note 6: Low dose rate testing has been performed on a wafer-by-wafer basis, per test method 1019 condition D of MIL-STD-883, with no enhanced low dose
rate sensitivity (ELDRS) effect.

Application Hints
The LM136 series voltage references are much easier to use
than ordinary zener diodes. Their low impedance and wide
operating current range simplify biasing in almost any circuit.
Further, either the breakdown voltage or the temperature co-
efficient can be adjusted to optimize circuit performance.
Figure 1 shows an LM136 with a 10k potentiometer for ad-
justing the reverse breakdown voltage. With the addition of
R1 the breakdown voltage can be adjusted without affecting
the temperature coefficient of the device. The adjustment
range is usually sufficient to adjust for both the initial device
tolerance and inaccuracies in buffer circuitry.
If minimum temperature coefficient is desired, two diodes can
be added in series with the adjustment potentiometer as
shown in Figure 2. When the device is adjusted to 2.490V the
temperature coefficient is minimized. Almost any silicon sig-
nal diode can be used for this purpose such as a 1N914,
1N4148 or a 1N457. For proper temperature compensation
the diodes should be in the same thermal environment as the
LM136. It is usually sufficient to mount the diodes near the
LM136 on the printed circuit board. The absolute resistance
of R1 is not critical and any value from 2k to 20k will work.
