| EN | 4 | 4 | Input | Enable pin. Drive EN greater than VEN(HI) to enable the regulator. Drive EN less than VEN(LOW) to put the regulator into low-current shutdown. Do not float this pin. If not used, connect EN to IN. |
| FB | 2 | — | Input | Feedback pin. Input to the control-loop error amplifier. This pin is used to set the output voltage of the device with the use of external resistors. For adjustable-voltage version devices only. |
| GND | 5 | 5 | — | Ground pin. |
| IN | 6 | 6 | Input | Input pin. For best transient response and to minimize input impedance, use the recommended value or larger capacitor from IN to ground as listed in the Recommended Operating Conditions table. Place the input capacitor as close to the IN and GND pins of the device as possible. |
| NC | — | 2 | — | No internal connection. For fixed-voltage version devices only. Ths pin can be floated but the device has better thermal performance with this pin tied to GND. |
| OUT | 1 | 1 | Output | Output pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger capacitor from OUT to ground. Follow the recommended capacitor value as listed in the Recommended Operating Conditions table. Place the output capacitor as close to the OUT and GND pins of the device as possible. |
| PG | 3 | 3 | Output | Power-good pin; open-collector output. Pullup this pin externally to the OUT pin or another voltage rail. The PG pin goes high when VOUT > VIT(PG,RISING), as discussed in the Electrical Characteristics table. The PG pin is driven low when VOUT < VIT(PG,FALLING), as discussed in the Electrical Characteristics table. Ths pin can be floated but the device has better thermal performance with this pin tied to GND. |
| Thermal pad | Pad | Pad | — | Exposed pad of the package. Connect this pad to ground or leave floating. Connect the thermal pad to a large-area ground plane for best thermal performance. |
