LM336Z25
Programmable Shunt Regulator
General Description
The LM336Z25 integrated circuits are precision 2.5V shunt reg-
ulators. The monolithic IC voltage reference operates as a low
temperature coefficient 2.5V zener with 0.2W dynamic imped-
ance. The monolithic IC voltage reference operates as a low
temperature coefficient 2.5V zener with 0.2W dynamic imped-
ance. A third terminal on the LM336Z25 allows the reference
voltage and temperature coefficient to be trimmed easily.
LM336Z25 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 LM336Z25 operate as shunt
regulators, they can be used as either a positive or negative
voltage reference.
