Notes:

5. Dropout voltage is the voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.

6. Device mounted on 2"*2" FR-4 substrate PC board, 2oz copper, with minimum recommended pad on top layer and thermal vias to bottom layer ground

plane.

7. Device mounted on 2"*2" FR-4 substrate PC board, 2oz copper,with minimum recommended pad layout.
