DESCRIPTION

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.
