TPS7B7702-Q1: start up time

Hi support team,

I would like to control the Vout (set to 4.5V) .

I want to know start up time of TPS7B7701/TPS7B7702.

Could  you teach me time per division of data sheet(revisionC) Typical Characteristics graph(Power up(1V/us))?

If power up graph's time per division is 100us/div,  this device has typical 200us soft start.

Could you please give me a typical soft start time and  a tolerance of this soft start time (typ=200us)?

Thanks.

Regards,

Toshimitsu
