The times are specified without a leakage current. For a leakage current of 10 A on the SVR pin, the delta time is specified. If the
capacitor value on the SVR pin changes with 30 %, the specified time will also change with 30 %. The specified time includes an ESR
of the capacitor on the SVR pin of up to 15 .
