0% Initial Tolerance Available Easily Trimmed for Minimum Temperature Drift Description The LM336-2.
5/LM336B-2.
5 integrated circuits are precision 2.
5V shunt regulators.
The monolithic IC voltage reference operates as a low temperature coefficient 2.
5V zener with 0.
2W dynamic impedance.
A third terminal on the LM336-2.
5/LM336B-2.
5 allows the reference voltage and temperature coefficient to be trimmed easily.
LM3362.
5/LM336B-2.
5 are useful as a precision 2.
5V low voltage reference for digital voltmeters, power supplies or OP-AMP circuitry.
The 2.
5V makes it convenient to obtain a stable reference from low voltage supplies.
Further, since the LM336-2.
5/LM336B-2.
5 operate as shunt regulators, they can be used as either a positive or negative voltage reference.
