1. A 250 mA load can be provided with inductor saturation current as a minimum of 0.9 A.
2. At -6.4 V, a 250 mA load can be provided with inductor saturation current as a minimum of 1.5 A. See Section 7.1.1.
Note:

All the above components refer to the typical application performance characteristics.
Operation of the device is not limited to the choice of these external components. Inductor
values ranging from 3.3 µH to 6.8 µH can be used together with the STOD13AS.
