Description The LM136-5.0/LM236-5.0/LM336-5.0 integrated circuits are precision 5.0V shunt regulator diodes. These monolithic IC voltage references operate as a low temperature coefficient 5.0V zener with 0.6 dynamic impedance. A third terminal on the LM136-5.0 allows the reference voltage and temperature coefficient to be trimmed easily.
The LM136-5.0 series is useful as a precision 5.0V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 5.0V makes it convenient to obtain a stable reference from low voltage supplies. Further, since the LM136-5.0 operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
The LM136-5.0 is rated for operation over -55°C to +125°C while the LM236-5.0 is rated over a -25°C to +85°C temperature range. The LM336-5.0 is rated for operation over a 0°C to +70°C temperature range. See the connection diagrams for available packages. For applications requiring 2.5V see LM136-2.5.
