TYPICAL PERFORMANCE CHARACTERISTICS
In most applications the SPX2931 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 100 mA. 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.
