I am simulating the TPS7A7200 using an imported netlist in a commonly available simulator. The issue is, when grounding the internal set resistors to program any output voltage, the resulting output voltage is always 300mV lower than the input voltage. Do you have a suggestion to resolve the problem or explain why this is occurring? Also when using an external divider I do not see this problem.
I have another question about the output capacitive loading of the part. In section 184.108.40.206 of the data sheet it states for output capacitors from 47 µF to 200 µF a feedforward capacitor of at least 220 pF must be used. The datasheet does not quote an absolute max for capacitance. In my application I would like to use an output capacitance of up to 300uF in ceramics. Is this problematic? What feedforward value should be used to compensate?
