Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| 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. |
| 6 | |||
| 7 | |||
| GND | 4 | — | Ground |
| EN | 5 | I | This pin turns the regulator on or off. If VEN ≥ VEN_HI the regulator is enabled. If VEN ≤ VEN_LO, the regulator is disabled. If not used, the EN pin can be connected to IN. Make sure that VEN ≤ VIN 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. |
