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.
