| PIN | TYPE | 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/NC | 2 | I | This pin is a 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. If using a fixed output this pin can either be left floating or connected to GND. |
| GND | 4 | — | Ground pin |
| IN | 8 | I | Regulator input supply pin. A capacitor > 0.1 μF must be tied from this pin to ground to assure stability. Connect 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 tracer 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. Connect 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. |
| Thermal pad | — | Solder to printed circuit board (PCB) to enhance thermal performance. Although the thermal pad can be left floating, connecting the thermal pad to the GND plane is highly recommended. | |
