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°C to +125°C while the LM236-2.5-N is
rated over a −25°C to +85°C temperature range.
The LM336-2.5-N is rated for operation over a 0°C to +70°C temperature range. See the
connection diagrams for available packages.
