OUT Figure 2. Simplified Schematic Block Diagram PIN FUNCTION DESCRIPTION Pin No. Pin Name Description 1 OUT Regulated output voltage pin. A small ceramic capacitor with minimum value of 1 F is needed from this pin to ground to assure stability. 2 GND Power supply ground. 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 IN Input pin. A small capacitor is needed from this pin to ground to assure stability. EPAD Exposed pad should be connected directly to the GND pin. Soldered to a large ground copper plane allows for effective heat removal.
