Note: Circuit diagram and the values are only tentative and subject to change.
(*1) Make sure that total capacitance of regulator output is greater than 10μF and meets the condition of ESR = 0.001 to 10Ω , in which voltage/temperature
dependence and unit differences are taken into consideration. Moreover, in case of electrolytic capacitor, high-frequency characteristics should be
sufficiently good.
(*2) These parts are necessary if output voltage of high-side switches gets lower than GND or higher than VCC. The same consideration is required on EXT1
through EXT4.
