With or without maximum external capacitance
Case 1: On/Off input is enabled and then input power
is applied(delay from instant at which VIN = VIN,
min until Vo = 10% of Vo, set )
Case 2: Input power is applied for at least one second
and then the On/Off input is enabled(delay from
instant at which Von/Off is enabled until Vo = 10% of
Vo, set)
Time for Vo to rise from
10% of Vo, set to 90% of Vo, set.
Notes: ¹ External capacitors may require using the new Tunable Loop^TM feature to ensure that the module is stable as well
as getting the best transient response. See the Tunable Loop^TM section for details.
