LM136A-2.5/LM136-2.5QML
Reference Diode
General Description
The LM136A-2.5/LM136-2.5 integrated circuit is a precision
2.5V shunt regulator diode. This monolithic IC voltage refer-
ence operates as a low-temperature-coefficient 2.5V zener
with 0.2Ω dynamic impedance. A third terminal on the
LM136-2.5 allows the reference voltage and temperature co-
efficient to be trimmed easily.
The LM136-2.5 is useful as a precision 2.5V low voltage ref-
erence for digital voltmeters, power supplies or op amp cir-
cuitry. 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.
