|OUT||1||O||Regulator output. A capacitor > 4.7 µF must be tied from this pin to ground to assure stability.|
|FB||2||O||This pin is the input to the control-loop error amplifier. It is used to set the output voltage of the device.|
|NC||3||—||Not internally connected. This pin must either be left open or tied to GND.|
|EN||5||I||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.
|PowerPAD||—||—||Solder to printed-circuit-board (PCB) to enhance thermal performance.
NOTE: The PowerPAD is internally connected to GND.
Although it can be left floating, TI highly recommends connecting the PowerPAD to the GND plane.
