| *1 |
For internal output transistor: This is an approximate value, because output current depends on conditions and external parts. |
| *2 |
The Fold-Back Protection circuit will execute current limitation while lowering operational frequency and continue operation for output short circuits, etc. When abnormal conditions are resolved, operating frequency becomes normal again and normal conditions are resumed. |
