LM136-5.0/LM236-5.0/LM336-5.0, 5.0V Reference Diode
General 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 0.6X 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 b55§C to
a125§C while the LM236-5.0 is rated over a b25§C to
a85§C temperature range. The LM336-5.0 is rated for operation
over a 0§C to a70§C temperature range. See the connection
diagrams for available packages. For applications
requiring 2.5V see LM136-2.5.
