SBVS128F June 2009 – December 2015 TPS727
The EN pin is marked with a dot for the 1.5-V, 1.8-V, 2.8-V, and 4.8-V versions of the YFF package. The GND pin is marked with a dot for all other voltage versions of the YFF package. Refer to YFF0004 Package Outline page included at the end of this document for dimensions of the YFF package. On the package outline, the shaded box indicates the location of ball A1 and does not correlate to any marking on the topside of the physical package.
|EN||A1||4||I||Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode, thus reducing the operating current to 120 nA, nominal.|
|IN||A2||6||I||Input pin. A small capacitor is needed from this pin to ground to assure stability. See in the Application Information section for more details.|
|NC||—||2, 5||—||No connection. This pin can be tied to ground to improve thermal dissipation.|
|OUT||B2||1||O||Regulated output voltage pin. A small 1-μF ceramic capacitor is needed from this pin to ground to assure stability. See in the Application Information section for more details.|
