General Description
The LM336Z5 and LM336BZ5 integrated circuits are precision
5.0V shunt regulators. The monolithic IC voltage reference
operates as a low temperature coefficient 5.0V zener with 0.6
:
dynamic impedance. A third terminal on the LM336Z5 and
LM336BZ5 allows the reference voltage and temperature coeffi-
cient to be trimmed easily.
The LM336Z5 and LM336BZ5 are useful as precision 5.0V low
voltage references which makes it convenient to obtain a stable
reference from low voltage supplies. Further, since the
LM336Z5 and LM336BZ5 operate as shunt regulators, they can
be used as either a positive or negative voltage reference.

Absolute Maximum Ratings
(Note 1)
Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The
parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating.
