SPX2930 150mA Low Dropout Voltage Regulator

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.
