Putting a resistor to sink 1mA can only give an approximate result as the load capacitance is not modelled, which is critical in finding out frequency response. It would give a better response than what you would get with inverters connected.

How do you generally assume/estimate the value of capacitance due to the load? say if i have to supply a digital circuit..how to go ahead with load cap value for simulation purposes?

I find it is better to use the digital circuit that going to drive as the resistor load bcoz for digital circuit ,the inpedance of LDO output always changes when input of the digital circuit switch from low to high and this will affect the loop gain of the LDO and also its phase margin. The loop gain of the LDO can vary a lot depend on the DC switching point of digiatl circuit.
