In case of output capacitance C3 is connected to Vout0, capacitance C3 connecting to Vout1 and Vout2 may be omitted.
The current value is just example for the explanation of this device function, please note that power dissipation should be taken
care when the system is designed or define the current value.
■
Power Dissipation
If the ambient temperature is exceed than 25 degree C , it is derated with derating factor of 1.24mW/Degree C.
