I use TPS7A8101 for 3.3V to 1.2V. EN connect to VIN. But some product 1.2V output delay 30-50ms when EN is enabled while most product 1.2V output immediately when EN is enabled. Below figure is my SCH and test result(red is EN and blue is 1.2V). So is this delay normal? Why is this result？ Thank you.
