TPS25200: [TPS25200] About programming the current-limit threshold

I'd like to use this device for current limiting on the SD Card power circuit.

Could you please tell me which should I use equation 1 or Figure17,18 in datasheet(SLVSCJ0C) page.15?

I think that both results don't match.

For example, I set the RILIM = 240kohm(F)

I got the following value Ios,when I use equation 1.

Ios,min = 340mA,Ios,typ = 402mA, Ios,max = 472mA

I got the following value Ios,when I use Fig.18.

Ios,min = 450mA,Ios,typ = 500mA, Ios,max = 550mA

so,I measured about current-limit threshold in our circuit.

<measurement condition>

 RILIM = 240k(F), Vout = 3.3V

Ios = 480mA.

Please refer to attached waveform.

1ch : Vout, 4ch:Iout
