Put decoupling capacitors near the IC.

When sag compensation function is used.

※

The application circuit is recommended for use.

When using the circuit, make sure to confirm the adequnacy of the characteristics.

Make sure to leave an adequate margin for external components includingstatic

and transitional characteristics as well as dispersion of the IC.

※

Make sure to take into account the tolerance characteristics of

the external components, as well as the IC power dissipation limits.

Place decoupling and bypass capacitors near the IC
