LM136-2.5/LM236-2.5/LM336-2.5V Reference Diode May 1998 LM136-2.5/LM236-2.5/LM336-2.5V Reference Diode General Description The LM136-2.5/LM236-2.5 and LM336-2.5 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 allows the reference voltage and temperature coefficient to be trimmed easily. The LM136-2.5 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 operates as a shunt regulator, it can be used as either a positive or negative voltage reference. The LM136-2.5 is rated for operation over - 55˚C to +125˚C while the LM236-2.5 is rated over a - 25˚C to +85˚C temperature range. The LM336-2.5 is rated for operation over a 0˚C to +70˚C...
