The LM336Z-5.0/NOPB is an Integrated Circuit, precision 5.0V shunt regulator diode. This monolithic IC voltage references operate as a low temperature coefficient 5.0V Zener with 0.6R dynamic impedance. A third terminal on the LM136-5.0 allows the reference voltage and temperature coefficient to be trimmed easily. The LM136-5.0 series is useful as a precision 5.0V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 5.0V makes it convenient to obtain a stable reference from low voltage supplies. Further, since the LM136-5.0 operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
