AP7343D-30FS4-7B Pin Configuration
| Pin | Name | Type | Description |
|---|---|---|---|
| 1 | VOUT | - | Power Output Pin |
| 2 | GND | - | Ground |
| 3 | EN | - | Enable Pin This pin should be driven either high or low and must not be floating. Driving this pin high enables the regulator, while pulling it low puts the regulator into shutdown mode |
| 4 | VIN | - | Power Input Pin |
| EP | Exposed Pad | - | In PCB layout, prefer to use large copper area to cover this pad for better thermal dissipation, then connect this area to GND or leave it open. However, do not use it as GND electrode function alone |

Notes:
- Stresses beyond those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to absolute-maximum-rated conditions for extended period may affect device reliability. Ratings apply to ambient temperature at +25°C. The JEDEC High-K board design used to derive this data was a 2 inch × 2 inch multilayer board with 1oz. internal power and ground planes and 2oz. copper traces on the top and bottom of the board.
