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 cir-

cuits 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 im-

pedance. A third terminal on the LM136-2.5 allows the refer-

ence 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 tem-

perature range.
