A small ceramic capacitor with minimum value of 1 F is need- ed from this pin to ground to assure stability. 2 2 GND Power supply ground. 3 3 EN Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode. 4 1 IN Input pin. A small capacitor is needed from this pin to ground to assure stability. 4 N/C Not connected. This pin can be tied to ground to improve thermal dissipation. EPAD Exposed pad should be connected directly to the GND pin. Soldered to a large ground cop- per plane allows for effective heat removal.
