Linear regulator LM1084 5.0V capacitors choice
Why don't you read the data sheet regarding capacitance on the LM1084? It clearly says that a minimum ESR corresponding to a 500kHz pole is required. If the capacitor has very low ESR such as a ceramic type, you can just add an appropriate series resistor. Ignoring the stability requirement can lead to oscillation- LDO regulators are not as forgiving as regular 3-terminal regulators.
