PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| 0P1V | 12 | I | When connected to GND, this pin adds 0.1 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 0P2V | 11 | I | When connected to GND, this pin adds 0.2 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 0P4V | 10 | I | When connected to GND, this pin adds 0.4 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 0P8V | 9 | I | When connected to GND, this pin adds 0.8 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 1P6V | 8 | I | When connected to GND, this pin adds 1.6 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 3P2V | 6 | I | When connected to GND, this pin adds 3.2 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 6P4V1 | 5 | I | When connected to GND, this pin adds 6.4 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| 6P4V2 | 4 | I | When connected to GND, this pin adds 6.4 V to the nominal output voltage of the regulator. Do not connect any voltage other than GND to this pin. If not used, leave this pin floating. |
| EN | 13 | I | Enable pin. The device is enabled when the voltage on this pin exceeds the maximum enable voltage, VEN(HI). If enable is not required, tie EN to IN. |
| GND | 7 | — | Ground |
| IN | 15, 16 | I | Input supply. A capacitor greater than or equal to 1 µF must be tied from this pin to ground to assure stability. A 10-µF capacitor is recommended to be connected from IN to GND (as close to the device as possible) to reduce circuit sensitivity to printed circuit board (PCB) layout, especially when long input traces or high source impedances are encountered. |
| NC | 2, 17-19 | — | This pin can be left open or tied to any voltage between GND and IN. |
| NR | 14 | — | Noise-reduction pin. When a capacitor is connected from this pin to GND, RMS noise can be reduced to very low levels. A capacitor greater than or equal to 10 nF must be tied from this pin to ground to assure stability. A 1-µF capacitor is recommended to be connected from NR to GND (as close to the device as possible) to maximize ac performance and minimize noise. |
| OUT | 1, 20 | O | Regulator output. A capacitor greater than or equal to 10 µF must be tied from this pin to ground to assure stability. A 47-µF ceramic output capacitor is highly recommended to be connected from OUT to GND (as close to the device as possible) to maximize ac performance. |
| SENSE/FB | 3 | I | Control-loop error amplifier input. This pin is the SENSE pin if the device output voltage is programmed using ANY-OUT (no external feedback resistors). This pin must be connected to OUT. Connect this pin to the point of load to maximize accuracy. This pin is the FB pin if the device output voltage is set using external resistors. See the Adjustable Operation Adjustable Operation section for more details. |
| PowerPAD | Pad | — | Connect the PowerPAD to a large-area ground plane. The PowerPAD™ is internally connected to GND. |
