Notes:

5. Recommend 0.01μF minimum load capacitance at output to suppress high frequency noise.

6. Test conditions for TO92-3L: No heat sink, no air flow.

7. Test conditions for SOP-8L: Device mounted on 2oz copper, minimum recommended pad layout, FR-4 PCB.

8. Test conditions for SOT89-3L: Device mounted on FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
