6、) and the VSS pin. For using low ESR capacitor (e.g. ceramic capacitors), please make sure that the output voltage is more than 1.7V. When the output voltage is from 1.3V to 1.6V, the output capacitor should be atantalum capacitor with a capacitance of 2.2F. We also suggest an input capacitor (Cthe
