TPS22990: Is there a maximum CT(pF)/output rise time spec?

I have followed the old threads but my question is not answered.

I am using TPS22990 as a Voltage Switch.

VIN = 5 V

VBIAS = 5V

ON = 5V 

All 5V are applied at the same time. Is this acceptable ? or do I need to sequence these ? VIN, VBIAS and then assert ON ?

I see a Vout T Rise of 1 ms under these conditions:

Ct = 0.47 uF

Cin = 1.0 uF

Cout at device = 0.1 uf

Cload is ~ 200 uF

I am expecting a T Rise on the VOUT of ~ 15 ms, but see 1 ms T rise

I added more Ct and still 1 ms.

Can this switch give me a T rise of 15 ms ? under these Voltage and load conditions ?

Thanks !!!
