Output Impedance Figure 10. Operation During Load Dump 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 determine the proper capacitor type and value. The high quality 100F aluminum electrolytic covers all general application circuits, this stability can be obtained with a tantalum electrolytic value of 47F. Another critical point of electrolytic characteristics is its performance over temperature. The SPX2930 is designed to operate starting at 40C which may not be true in the case of electrolytic. Higher temperatures generally no problem. The electrolytic. type in aluminum will freeze around -30C. 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 25C, the Date: 05/25/04 SPX2930 150mA Low Dropout Voltage Regulator (c) Copyright 2002 Sipex Corporation 4 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.
