The LM336Z25 integrated circuit is a precision 2.5 V
shunt regulator. The monolithic IC voltage reference
operates as a low temperature coefficient 2.5 V Zener
with 0.2 Ω dynamic impedance. A third terminal on the
LM336Z25 allows the reference voltage and temperature
coefficient to be trimmed. LM336Z25 is useful as a precision 2.5 V low-voltage reference for digital voltmeters,
power supplies, or OP-AMP circuitry. The 2.5 V makes it
convenient to obtain a stable reference from low-voltage
supplies. Further, since the LM336Z25 operates as a
shunt regulator, it can be used as either a positive or
negative voltage reference.
