1) Minimum value given is needed for regulator stability; application might need higher capacitance than the minimum.
2) Minimum value given is needed for regulator stability; application might need higher capacitance than the minimum.
3) Selection of external switching MOSFET is crucial and the V_IVCC,RTH,d min. as worst case V_GS must be considered.
