Pin Functions
| PIN | I/O | DESCRIPTION | |
|---|---|---|---|
| NAME | NO. | ||
| DELAY | 7 | O | Delay pin. Connect a capacitor to GND to adjust the PG delay time; leave open if the reset function is not needed. |
| EN | 5 | I | Enable pin. This pin turns the regulator on or off. If VEN ≥ VEN_HI, the regulator is enabled. If VEN ≤ VEN_LO, the regulator is disabled. If not used, the EN pin can be connected to IN. Make sure that VEN ≤ VIN at all times. |
| FB/DNC | 2 | I | For the adjustable version (TPS7A1601), the feedback pin is the input to the control-loop error amplifier. This pin is used to set the output voltage of the device when the regulator output voltage is set by external resistors. For the fixed voltage versions: Do not connect to this pin. Do not route this pin to any electrical net, not even GND or IN. |
| GND | 4 | GND | Ground pin. |
| IN | 8 | IN | Regulator input supply pin. A capacitor ≥ 0.1 µF must be tied from this pin to ground to assure stability. TI recommends connecting a 10-µF ceramic capacitor 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 | 6 | — | This pin can be left open or tied to any voltage between GND and IN. |
| OUT | 1 | O | Regulator output pin. A capacitor ≥ 2.2 µF must be tied from this pin to ground to assure stability. TI recommends connecting a 10-µF ceramic capacitor from OUT to GND (as close to the device as possible) to maximize AC performance. |
| PG | 3 | O | Power-good pin. Open collector output; leave open or connect to GND if the power-good function is not needed. |
| PowerPAD | — | — | Solder to printed-circuit-board (PCB) to enhance thermal performance. Although it can be left floating, TI highly recommends connecting the PowerPAD to the GND plane. |
