PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |||
|---|---|---|---|---|---|
| NAME | NO. | ||||
| DGN | DRV | KVU | |||
| DNC | — | 5 | 4 | — | Do not connect to a biased voltage. Tie this pin to ground or leave floating. |
| EN | 2 | 2 | 2 | I | Enable input pin. Drive EN greater than VIH to turn on the regulator. Drive EN less than VIL to put the low-dropout (LDO) into shutdown mode. |
| GND | 4, 5, 6 | 3,4 | 3, TAB | — | Ground reference |
| IN | 1 | 1 | 1 | I | Input power-supply pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground as listed in the Recommended Operating Conditions table and the Input Capacitor section. Place the input capacitor as close to the output of the device as possible. |
| NC | 3, 7 | — | — | — | Not internally connected |
| OUT | 8 | 6 | 5 | O | Regulated output voltage pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger ceramic capacitor from OUT to ground; see the Recommended Operating Conditions table and the Output Capacitor section. Place the output capacitor as close to output of the device as possible. |
| Thermal pad | — | Connect the thermal pad to a large-area GND plane for improved thermal performance. | |||
