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.
