LM113/LM313 Reference Diode

LM113/LM313 Reference Diode

December 1994

General Description

The LM113/LM313 are temperature compensated, low volt­age reference diodes. They feature extremely-tight regula­tion 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 siliconÐthe ener­gy-band gap voltageÐmakes it useful for many tempera­ture-compensation and temperature-measurement func­tions.

Note 1: For operating at elevated temperatures, the device must be derated based on a 150§C maximum junction and a thermal resistance of 80
case or 440

Note 2: These specifications apply for T
inch. Kelvin contact sockets are also recommended. The diode should not be operated with shunt capacitances between 200 pF and 0.1 mF, unless isolated by at
least a 100X resistor, as it may oscillate at some currents.
