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.
