Here is the datasheet http://www.onsemi.com/pub/Collateral/FDN358P-D.PDF , where it says in the Absolute Maximum Ratings that you can draw continuously about ***1.5[A] ***... but this is not the only information to be considered. Since the board (safe) design supports a 500[mA] LDO Voltage Regulator, you are with 500[mA] on the safe - cool(er) - side. You may go higher... but the specs do not say a thing about voltages lower than 4.5[V] 200[mOhm]. With raising on-Resistance more heat has to be dissipated...
For running a GPS - 60[mA], you are more then fine...
