| PIN | TYPE | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | DBV | DYB | ||
| ADJ/EN | 1 | 1 | I | Adjustable or enable input pin. Connect the external reference voltage to this pin. This pin connects to the error amplifier internally. A low signal below VIL disables the device, and a high signal above VIH enables the device. Connect the voltage reference directly or with a voltage divider for lower output voltages. To compensate for line influences, place a 0.1-μF capacitor close to this pin. |
| GND | 2 | 2, 5 | G | Ground pin. |
| IN | 3 | 3 | I | Input power-supply voltage pin. This pin is the device supply. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to GND as listed in the Recommended Operating Conditions table. Place the input capacitor as close to the input of the device as possible to compensate for line influences. |
| NC | 5 | — | — | NC pin. This pin is not internally connected. This pin can either be left floating or connected to GND for improved thermal performance. |
| OUT | 4 | 4 | O | Tracker output voltage pin. A capacitor is required from OUT to GND for stability. For best transient response, use the nominal recommended value or larger ceramic capacitor from OUT to GND; see the Recommended Operating Conditions table. Place the output capacitor as close to output of the device as possible. |
