Feature Specifications (cont.)

Parameter

Turn-On Delay and Rise Times

(VIN=VIN, nom, IO=IO, max , VO to within ±1% of steady state)

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)

Output voltage Rise time (time for Vo to rise from

10% of Vo, set to 90% of Vo, set)

Output voltage overshoot (TA = 25oC

VIN= VIN, min to VIN, max,IO = IO, min to IO, max)

With or without maximum external capacitance
