(*2)

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 10

μF 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.
