APPLICATION INFORMATION
The SPX2930 requires an output capacitor for
device stability. The value required varies greatly
depending upon the application circuit and other
factors. The high frequency characteristics of
electrolytic capacitors depend greatly on the
type and also on the manufacturer. Sometimes
only bench testing is the only means to deter-
mine the proper capacitor type and value. The
high quality 100
F aluminum electrolytic cov-
ers all general application circuits, this stability
can be obtained with a tantalum electrolytic
value of 47
F.
Another critical point of electrolytic character-
istics is its performance over temperature. The
SPX2930 is designed to operate starting at -
40
°C which may not be true in the case of
electrolytic. Higher temperatures generally no
problem. The electrolytic. type in aluminum
will freeze around -30
°C. This could cause an
oscillation at output of regulator. At a lower
temperature requirement by many applications
the capacitor should maintain its performance.
So as a result, for an application which regulator
junction temperature does not exceed 25
°C, the
