Reference Data

Reference data are intended for use in selecting external parts to the IC.

The information therefore provides

characteristic data in which external parts are selected with a view of wide variety of IC applications. All data shows

typical value.

*1. CDRH5D18 + NDS335N + RB491D: For small and thin parts of which height is 2 mm or shorter (The maximum current of

an external part should be set to 1.7 A.)

*2. CDRH124 + FTS2001 + RBO81L-20: For heavy load current (The maximum current of an external part should be set to

4.5 A.)
