A small ceramic capacitor with minimum value of 1 mF is needed from thispin to ground to assure supply EN over V turns on the Regulator . Driving EN below V puts the Regulator into pin. A small capacitor is needed from this pin to ground to assure stability. EPADE xposed pad should be connected directly to the GND pin.
