Table 4-6 Pin FMA for Device Pins Short-Circuited to Ground
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| OUT | 3 | Regulation is not possible, the device operates at current limit. The device can cycle in and out of thermal shutdown. | B |
| 1 | |||
| IN | 2 | Power is not supplied to the device. System performance depends on upstream current limiting. | B |
| 3 | |||
| GND | 1 | No effect. Normal operation. | D |
| 2 |
