4 Pin Configuration and Functions

| PIN | TYPE(1) | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | DCY | DRB | ||
| EN | 2 | 7 | I | Enable pin. The device is disabled when the enable pin becomes lower than the enable logic input low level (VIL). To ensure the device is enabled, the EN pin must be driven above the logic high level (VIH). This pin should not be left floating as this pin is high impedance if it is left floating the part may enable or disable. |
| GND | 4 | 5 | G | Ground pin. Connect this pin to the thermal pad with a low-impedance connection. |
| FB/NC | — | 2 | I | Feedback pin when using an external resistor divider or an NC pin when using the device with a fixed output voltage. When using the adjustable device this pin must be connected through a resistor divider to the output for the device to function. |
| NC | __ | 3, 4, 6 | __ | No internal connection. Connect these pins to GND for the best thermal performance. |
| IN | 1 | 8 | I | Input power-supply voltage 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 input of the device as possible. |
| OUT | 3 | 1 | 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. If using a high ESR capacitor, decouple the output with a 100-nF ceramic capacitor. |
| Thermal pad | — | Pad | — | Thermal pad. Connect the pad to GND for the best possible thermal performance. See the Layout section for more information. |
(1) I = input; O = output; G = ground.
