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 TO3 and TO66 packages, at the junction of the
wide and narrow portion of the output lead for the SMD packages, and 1/8" below the base of the package on the output pin of the TO257 package.
2) Test Conditions unless otherwise stated: VIN VOUT = 5V , IOUT = 0.5A , PMAX = 20W , IMAX = 1.5A, VMAX = 40V for standard series , 50V for HV series.

APPLICATIONS INFORMATION
High Stability Regulator
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.
Multiple Tracking Regulators
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 V
OUT
/ 1.25V compared to a standard regulator,
so regulator #1 should be the one which has the lowest load
current.
* Solid Tantalum
** R1 or R5 may be trimmed slightly to improve tracking.
