Notes:

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

For any output voltage less than 2.5V, the minimum VIN operating voltage is the limiting factor.

5. The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the adjust

voltage tolerance specification.

6. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper with minimum recommended pad layout.
