LM336Z-2.5/LFT7

The LM136- 2.5- N/LM236- 2.5- N and LM336- 2.5- N integrated circuits are precision 2.5V shunt regulator diodes. These monolithic IC voltage references operate as a low- temperature- coefficient 2.5V zener with 0.2Ω dynamic impedance. A third terminal on the LM136- 2.5- N allows the reference voltage and temperature coefficient to be trimmed easily. The LM136- 2.5- N series is useful as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 2.5V make it convenient to obtain a stable reference from 5V logic supplies. Further, since the LM136- 2.5- N operates as a shunt regulator, it can be used as either a positive or negative voltage reference. The LM136- 2.5- N is rated for operation over - 55℃ to +125℃ while the LM236- 2.5- N is rated over a - 25℃ to +85℃ temperature range. The LM336- 2.5- N is rated for operation over a 0℃ to +70℃ temperature range.
