Notes:

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

5. This specification is guaranteed by design.

6. Test condition for SOT26: Device mounted on FR-4 substrate PC board, with minimum recommended pad layout

7. Test condition for DFN2018-6: Device mounted on FR-4 2-layer board,2oz copper, with minimum recommended pad on top layer and 3 vias to

bottom layer.
