General Description
The LM199 series are precision, temperature-stabilized
monolithic zeners offering temperature coefficients a factor
of ten better than high quality reference zeners. Constructed
on a single monolithic chip is a temperature stabilizer circuit
and an active reference zener. The active circuitry reduces
the dynamic impedance of the zener to about 0.5
and
allows the zener to operate over 0.5 mA to 10 mA current
range with essentially no change in voltage or temperature
coefficient. Further, a new subsurface zener structure gives
low noise and excellent long term stability compared to
ordinary monolithic zeners. The package is supplied with a
thermal shield to minimize heater power and improve tem-
perature regulation.
The LM199 series references are exceptionally easy to use
and free of the problems that are often experienced with
ordinary zeners. There is virtually no hysteresis in reference
voltage with temperature cycling. Also, the LM199 is free of
voltage shifts due to stress on the leads. Finally, since the
unit is temperature stabilized, warm up time is fast.
The LM199 can be used in almost any application in place of
ordinary zeners with improved performance. Some ideal
applications are analog to digital converters, calibration stan-
dards, precision voltage or current sources or precision
power supplies. Further in many cases the LM199 can re-
place references in existing equipment with a minimum of
wiring changes.
The LM199 series devices are packaged in a standard her-
metic TO-46 package inside a thermal shield. The LM199 is
rated for operation from 55C to +125C while the LM299 is
rated for operation from 25C to +85C and the LM399 is
rated from 0C to +70C.
