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. LM336-

2.5/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.
