LM113/LM313 Reference Diode
General Description
The LM113/LM313 are temperature compensated, low volt-
age reference diodes. They feature extremely-tight regula-
tion over a wide range of operating currents in addition to an
unusually-low breakdown voltage and good temperature
stability.
The diodes are synthesized using transistors and resistors
in a monolithic integrated circuit. As such, they have the
same low noise and long term stability as modern IC op
amps. Further, output voltage of the reference depends only
on highly-predictable properties of components in the IC; so
they can be manufactured and supplied to tight tolerances.

The characteristics of this reference recommend it for use in
bias-regulation circuitry, in low-voltage power supplies or in
battery powered equipment. The fact that the breakdown
voltage is equal to a physical property of siliconDthe ener-
gy-band gap voltageDmakes it useful for many tempera-
ture-compensation and temperature-measurement func-
tions.
