APPLICATION INFORMATION  
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  
The SPX2930 requires an output capacitor for  
devicestability.Thevaluerequiredvariesgreatly  
dependingupontheapplicationcircuitandother  
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 100µF aluminum electrolytic cov-  
ers 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 tem-  
perature range.  
In most applications the SPX2930 is operating  
at few milliamps. In these applications the out-  
put 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 mini-  
mum of 0.6 volts required at the input of regula-  
tor above the output to keep the power dissipa-  
tion and die heating to its minimum. After the  
value for the capacitor has been determined for  
actual use, the value should be doubled.
