Switch (Output): Internal power MOSFET output switches.
Enable (Input). Logic low will shut down the device, reducing the quiescent
current to less than 4µA. Do not leave floating.
No Connect
Connect to V_OUT to sense output voltage.
Feed Forward Capacitor. Connect a 560pF capacitor from V_OUT to CFF pin.
Analog Ground.
Supply Voltage (Input): Requires bypass capacitor to GND.
Power Ground.
