A search shows a fair number of parts in our USB power switch portfolio.  These parts can be used for other applications besides USB.    Generally the TPS2550 - TPS2560 are programmable, using resistor programming.  The next parts that are fixed current limit that you should look at would be TPS2068/69.  There are variations with multipe switches and enable polarities.

The Power Management Guide (slvt145j)  also has a number of nice figures and tables.  See page 65, 66 - note the currents shown are typical limits, not rated continuous current.  Pages 61, 62 show a line of simpler load switches as well.
