Notes: 4. Recommend 0.01µF minimum load capacitance at output to suppress high frequency noise.
5. Test conditions for TO92: No heat sink, no air flow.
6. Test conditions for SO-8: Device mounted on 2oz copper, minimum recommended pad layout, FR-4 PCB.
7. Test conditions for SOT89: Device mounted on FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
