Pin Configuration
| PIN | PIN | I/O | DESCRIPTION |
|---|---|---|---|
| NAME | NO. | I/O | DESCRIPTION |
| OUT | 1 | O | Regulator output. A capacitor > 4.7 μF must be tied from this pin to ground to assure stability. |
| FB | 2 | O | This pin is the input to the control-loop error amplifier. It is used to set the output voltage of the device. |
| NC | 3 | - | Not internally connected. This pin must either be left open or tied to GND. |
| NC | 6 | - | Not internally connected. This pin must either be left open or tied to GND. |
| NC | 7 | - | Not internally connected. This pin must either be left open or tied to GND. |
| GND | 4 | - | Ground |
| EN | 5 | I | This pin turns the regulator on or off. If V EN ≥ V EN_HI the regulator is enabled. If V EN ≤ V EN_LO , the regulator is disabled. If not used, the EN pin can be connected to IN. Make sure that V EN ≤ V IN at all times. |
| IN | 8 | I | Input supply |
| PowerPAD | - | - | Solder to printed-circuit-board (PCB) to enhance thermal performance. NOTE: The PowerPAD is internally connected to GND. Although it can be left floating, TI highly recommends connecting the PowerPAD to the GND plane. |

Typical Application
One of the primary applications of the TPS7A4001 device is to provide transient voltage protection to sensitive circuitry that may be damaged in the presence of high-voltage spikes.
This transient voltage protection can be more cost-effective and compact compared to topologies that use a transient voltage suppression (TVS) block.
