Overview
LM199/LM299/LM399 Precision Reference April 2005 LM199/LM299/LM399 Precision Reference 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.
5Ω 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 ord...
