APPLICATION INFORMATION
The SPX3819 requires an output capacitor for capacitor works in most application circuits, but device stability. Its value depends upon the the same stability often can be obtained with a application circuit. In general, linear regulator 1μF tantalum electrolytic. stability decreases with higher output currents. With the SPX3819 adjustable version, the In applications where the SPX3819 is sourcing minimum value of output capacitance is a less current, a lower output capacitance may be function of the output voltage. The value sufficient. For example, a regulator outputting decreases with higher output voltages, since only 10mA, requires approximately half the closed loop gain is increased. capacitance as the same regulator sourcing 150mA.
TYPICAL APPLICATIONS CIRCUITS
Bench testing is the best method for determining the proper type and value of the For fixed voltage options only. A 10nF capacitor capacitor since the high frequency on the BYP pin will significantly reduce output characteristics of electrolytic capacitors vary noise, but it may be left unconnected if the widely, depending on type and manufacturer. A output noise is not a major concern. The high quality 2.2μF aluminum electrolytic SPX3819 start-up speed is inversely proportional to the size of the BYP capacitor. 7/13 Rev. 2.0.5
