(Note 1) Consider tolerance, temperature characteristic and DC bias properties not to become less than the minimum

(Note 2) Consider tolerance and temperature characteristic not to become bigger than the maximum.

(Note 3) Total capacity attached to VO1 node must not exceed 40 uF.

(Note 4) Choose an inductor of 3.3 µH (Typ). It must not become less than 2.0 µH including tolerance, temperature characteristic and DC

superposition characteristics.

(Note 5) Choose an inductor of 1.5 µH (Typ) or 2.2 µH (Typ). It must not become less than 1.0 µH including tolerance, temperature characteristic

and DC superposition characteristics.
