LM336Z5 • LM336BZ5 Programmable Shunt Regulator
February 2002
Revised August 2005
LM336Z5 • LM336BZ5
Programmable Shunt Regulator
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.
