Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| EN | 2 | I | Enable pin. Driving EN high turns on the device (if driven low, EN turns off the device). EN must not be left floating and can be connected to IN if not used. |
| GND | 3 | — | Ground |
| IN | 1 | I | Input supply. A capacitor greater than or equal to 10 µF must be tied from this pin to ground to assure stability. This configuration is especially important when long input traces or high source impedances are encountered. TI recommends using X5R- or X7R-type dielectrics to minimize the temperature variations inherent to capacitors. |
| NR | 4 | O | 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. TI recommends connecting a 1-µF capacitor from NR to GND (as close to the device as possible) to maximize AC performance and minimize noise. TI recommends using X5R- or X7R-type dielectrics to minimize the temperature variations inherent to capacitors. In addition, when a resistor is connected from this pin to GND or IN, the device input-to-output voltage can be programmed; see Feature Description for details. |
| OUT | 6 | O | Regulator output. A capacitor greater than or equal to 10 µF must be tied from this pin to ground to assure stability. TI recommends using a X5R- or X7R-type dielectrics to minimize the temperature variations inherent to capacitors. |
| PowerPAD™ | — | — | Connect the PowerPAD to the ground plane for improved thermal performance. |
| SENSE | 5 | I | Control-loop error amplifier input. This pin must be connected to OUT. TI recommends connecting SENSE at the point of load to maximize accuracy. |
