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 0.6Ω 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 opamp 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.
