Operational Notes - continued

12. Regarding the Input Pin of the IC

In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The operation

of these parasitic elements can result in mutual interference among circuits, operational faults, or physical damage.

Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an input pin lower

than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input terminals when no power

supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the input pins have

voltages within the values specified in the electrical characteristics of this IC.

13. Ceramic Capacitor

When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with

temperature and the decrease in nominal capacitance due to DC bias and others.

14. Area of Safe Operation (ASO)

Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe

Operation (ASO).
