HI,letan,
in general, we defined Io,max by output voltage variance ,take TPS79301 (TI) as example ,
as it provide 200mA, it ratio ( [Vo,nom-Vo]/[Vo,nom]) increase to 1%,
(see figure 2 in spec.)
(Vo,nom: normal output voltage )
so , TI says the IP can provide max current to 200mA,
if you use the IP and you can tolerate the
ratio to 2%,for example, then you can use it up to
more than 200mA
try to see more IP provider's spec, you learn more form them!!
