This is the datasheet of TPS7A8101 LDO I am analyzing. In the datasheet, start-up time of the LDO is given as 80 ms for given conditions.

My question is, how can I calculate the turn-off time of the LDO. I was doing a shut-down timing sequence diagram for my circuit and came across this LDO. I believe LTSpice simulation can get an idea of turn-off time. But not sure about that.

How can I find the turn off time of an LDO?
