The capacitor shall be application circuit for the SE85XX devices. placed as close as possible to VIN pin, and the wide Please keep in mind that in-rush current can copper trace is also recommended. push up the Vin overshoot by as much as OUTPUT CAPACITOR 50%. For example, when Vin=30V, the in-rush The recommended is 10uF ceramic capacitor. The minimum capacitance for stable and correct operation is 1μF. The higher the value of this output capacitor, caused spike voltage can be as high as 45V. Therefore the voltage rating of Cin needs to be higher than 50% of the application. the lower the ripple during the operations. The output capacitor should be placed as close to the Output Pin as possible. The wide copper trace is recommended. NO-LOAD STABILITY The SE85XX will remain stable and in regulation with no external load. This is especially important in CMOS RAM keep-alive applications. FOLD-BACK SHORT-CIRCUIT PROTECTION In live insertion application, it is suggested that R, C1 are selected as following： When short-circuit occurs, SE85XX will fold back 1.C1=10μF ~ 100μF ceramic or electrolytic the short-circuit currents to a pre-determined lower capacitor with maximum voltage greater than level, This will reduce excessive heat in otherwise 50V, R=0 large current conditions. This feature provides 2.If the average current is known, for example a another level of protection to IC itself and also the t 10mA, then for an input voltage of 20V, the C1 whole system. =1μF ~ 10μF ceramic or electrolytic with maxim um voltage greater than 40V and R=1KΩ in the type of 1206 at 1/4W rating can be selected.
