| NAME | DRB (Fixed) | DRB (Adjustable) | DRB (Fixed) B Version | DRB (Adjustable) B Version | KVU (Fixed) | KVU (Adjustable) | ||
| EN | 7 | 7 | 6 | 6 | 1 | 1 | Input | Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device. Do not float this pin. If not used, connect EN to IN. |
| FB | — | 2 | — | 2 | — | 5 | 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. Do not float this pin. For adjustable-voltage version devices only. |
| GND | 5 | 5 | 5 | 5 | 3 | 3 | — | Ground pin. This pin must be connected to ground on the board. |
| IN | 8 | 8 | 8 | 8 | 2 | 2 | Input | Input pin. For best performance, place the nominal recommended value or larger ceramic capacitor from IN to GND; see the Recommended Operating Conditions table. Place the input capacitor as close to the input of the device as possible. |
| NC | 2, 3, 4, 6 | 3, 4, 6 | 2, 3, 4, 7 | 3, 4, 7 | 5 | — | — | No connect pin. This pin is not internally connected. Connect to ground for best thermal performance or leave floating. |
| OUT | 1 | 1 | 1 | 1 | 4 | 4 | Output | A 0.47-µF or greater effective capacitance is required from OUT to ground for stability. For best transient response, use a 1-µF or larger ceramic capacitor from OUT to ground. Place the output capacitor as close to output of the device as possible; see the Recommended Operating Conditions table. |
| Thermal Pad | Pad | Pad | Pad | Pad | Pad | Pad | — | The thermal pad is electrically connected to the GND pin. Connect the thermal pad to a large-area GND plane for improved thermal performance. |
