LM136-5.0/LM236-5.0/LM336-5.0
5.0V Reference Diode
General Description
The LM136-5.0/LM236-5.0/LM336-5.0 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 tempera-
ture coefficient to be trimmed easily.
The LM136-5.0 series is useful as a precision 5.0V low volt-
age 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.
The LM136-5.0 is rated for operation over −55˚C to +125˚C
while the LM236-5.0 is rated over a −25˚C to +85˚C tem-
perature range. The LM336-5.0 is rated for operation over a
0˚C to +70˚C temperature range. See the connection dia-
grams for available packages. For applications requiring
2.5V see LM136-2.5.
