3 / 8 page 3 May5-07 SPX52300mALowDropoutVoltageRegulator ©2007SipexCorporation External Capacitors The stability of the SPX52 requires a 2.2µForgreatercapacitorbetweenoutput andground.Oscillationcouldoccurwithout this capacitor.Most types of tantalum or aluminum electrolytic works fine here. For operationsofbelow-25°Csolidtantalumis recommended since the many aluminum typeshaveelectrolytesthatfreezeatabout -30°C. The ESR of about 5Ω or less and resonantfrequencyabove500kHzarethe mostimportantparametersinthevalueof thecapacitor.Thecapacitorvaluecanbe increasedwithoutlimit. The SPX52, unlike other low dropout regulatorswillremainstableandinregula- tionwithnoloadinadditiontotheinternal voltage divider.This feature is especially important in applications like CMOS RAM keep-alive. Ifthereismorethan0inchesofwirebe- tween the input and the AC filter capacitor, orifabatteryisusedastheinput,thena 0.µF tantalum or aluminum electrolytic capacitorshouldbeplacedfromtheinput totheground.
