Notes:

3. Dropout voltage is defined as the input to output differential voltage. Dropout is measured at constant junction temperature by using pulsed ON

4. Current limit is measured at constant junction temperature by using pulsed testing with a low ON time.

5. Regulation is measured at constant junction temperature by using pulsed testing with a low ON time.

6. Guaranteed by design.

7. Test conditions for SOT25: Device mounted on FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
