Pin Function
Output voltage. A minimum 10F capacitor should be placed directly at this pin.
No internal connection.
Feedback voltage input. Connect an external resistor divider to this pin for output
voltage setting. If this pin is connected to the VOUT pin, the output voltage will be
set at 1.2V.
Ground. The exposed pad must be soldered to a large PCB and connected to GND
for maximum the power dissipation.
Enable control input. Connecting this pin to logic high enables the regulator or
driving this pin low puts it into shutdown mode. EN can be connected to VIN if not
used. (EN pin is not allowed to be left floating)
Internal connection. Leave floating and do not make connection to this pin.
Supply voltage input. Connect a minimum 10F ceramic capacitor at this pin.
