*1. A time interval example for a typical application circuit with no load. The series regulator and DC/DC converter output voltage rise times may vary with
the load current, output capacitance, and other conditions.
*2. The soft start time is the interval during which the output current is limited internally in the IC, and is different from the series regulator and DC/DC con-
verter output raise time.
