Description

The LM336Z25 integrated circuit is a precision 2.5 V shunt regulator. The monolithic ICvoltage 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.
