APPLICATION INFORMATION
Another critical point of electrolytic characteristics 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
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 determine the proper capacitor type and value. The
high quality 100µF aluminum electrolytic covers all general application circuits, this stability
can be obtained with a tantalum electrolytic
value of 47µF.

output capacitor can be reduced by the factor of
two over the value needed for the entire temperature range.
In most applications the SPX2930 is operating
at few milliamps. In these applications the output capacitance can be further reduced. For
example, when the regulator is running at 10mA
output current the output capacitance value is
half compared to the same regulator that is
running at 100mA. The value decreases with
higher output voltages, since the internal loop
gain is reduced.
The worst case occurs at the lower temperature
and maximum operating currents, the entire
circuit and the electrolytic, should be cooled
down to the minimum temperature. The minimum of 0.6 volts required at the input of regulator above the output to keep the power dissipation and die heating to its minimum. After the
value for the capacitor has been determined for
actual use, the value should be doubled.
