Description
Enable pin: This pin allows on/off control of the regulator. To disable the device, connect to
GND. If this function is not in use, connect to Vin. Internal 5 MW Pull Down resistor is con-
nected between EN and GND.
Power Supply Ground (Pins are fused for the DFN6 package). Pins 2, 5 and EPAD are con-
nected together through the lead frame in the DFN6 package.
