|DNC||7||—||Do not connect. Do not route this pin to any electrical net, not even GND or IN.|
|EN||5||I||This pin turns the regulator on or off. If VEN ≥ VEN(high), the regulator is enabled.
If VEN ≤ VEN(low), the regulator is disabled. The EN pin can be connected to IN, if not used. VEN ≤ VIN.
|FB||2||I||This pin is the input to the error amplifier. FB is used to set the output voltage of the device.|
|NC||3||—||Not internally connected. This pin can either be left open or tied to GND.|
|NR/SS||6||—||Noise-reduction pin. Connecting an external capacitor to this pin bypasses noise generated by the internal band gap. This capacitor allows RMS noise to be reduced to very low levels and also controls the soft-start function.|
|OUT||1||O||Regulator output. A capacitor ≥ 2.2 μF must be tied from this pin to ground to ensure stability.|
|PowerPAD||—||Must either be left open or tied to ground.
Solder to the printed-circuit-board (PCB) plane to enhance thermal performance.
