We are implementing TPS2553-1 power switch as current limiter below a maximum current limit as shown in the figure 26 in the data sheet.The circuit parameters are as follows :
Cin = 0.1microF
Rfault = 100kOhm
Rload = 10kOhm , Cload = 100microF
Rlim = 22kOhm
Vin = 5V
The output across load is about 2.25V which is much less than the input.The voltage across the input and output pins of the TPS2553-1 is 2.75V.The output voltage decreases with the load resistance.
