Description

The LM336-5.0 / LM336B-5.0 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 ohm dynamic impedance. A third terminal on

the LM336-5.0/LM336B-5.0 allows the reference voltage

and temperature coefficient to be trimmed easily.

The LM336-5.0/LM336B-5.0 are useful as a precision 5.0V

low voltage references which makes it convenient to obtain a

stable reference from low voltage supplies. Further, since the

LM336-5.0/LM336B-5.0 operate as shunt regulators, they

can be used as either a positive or negative voltage reference.
