5.0V Reference Diode
General Description
Features
The LM136A-5.0QML/LM136-5.0QML integrated circuits are
precision 5.0V shunt regulator diodes. These monolithic IC
voltage references operate as a low temperature coefficient
5.0V zener with 0.6Ω dynamic impedance. A third terminal on
the LM136-5.0 allows the reference voltage and temperature
coefficient to be trimmed easily.
The LM136-5.0 series is useful as a precision 5.0V low voltage reference for digital voltmeters, power supplies or op amp
circuitry. The 5.0V makes it convenient to obtain a stable reference from low voltage supplies. Further, since the
LM136-5.0 operates as a shunt regulator, it can be used as
either a positive or negative voltage reference.

LM136A-5.0QML/LM136-5.0QML
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)/
θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 100pF discharged through 1.5KΩ
Note 4: Guaranteed, not tested.

Application Hints
The LM136-5.0 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 coefficient can be adjusted to optimize circuit performance.
Figure 1 shows an LM136-5.0 with a 10k potentiometer for
adjusting 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, four diodes can
be added in series with the adjustment potentiometer as
shown in Figure 2. When the device is adjusted to 5.00V the
temperature coefficient is minimized. Almost any silicon signal 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
LM136-5.0. It is usually sufficient to mount the diodes near
the LM136-5.0 on the printed circuit board. The absolute resistance of the network is not critical and any value from 2k
to 20k will work. Because of the wide adjustment range, fixed
resistors should be connected in series with the pot to make
pot setting less critical.
