1) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to
heating effects are covered under thermal regulation specifications. Load regulation is measured at a point 1/8” from the bottom of
the package for the TO–3 and TO–66 packages, at the junction of the wide and narrow portion of the output lead for the SMD1
package, and 1/8” below the base of the package on the output pin of the TO–257 package.

APPLICATIONS INFORMATION
High Stability Regulator
Multiple Tracking Regulators
The output stability, load regulation, line regulation, thermal
regulation, temperature drift, long term drift, and noise, can be
improved by a factor of 6.6 over the standard regulator
configuration. This assumes a zener has 20PPM/°C maximum
drift and about 10 times lower noise than the regulator.
In the application shown below, regulator #2 to “N” will track
regulator #1 to within ±24mV initially, and to ±60mV over all load,
line, and temperature conditions.
If any regulator output is shorted to ground, all other
outputs will drop to -2V. Load regulation of regulators 2 to “N” will
be improved by VOUT / 1.25V compared to a standard regulator,
so regulator #1 should be the one which has the lowest load
current.
