Pin Name
Switch (Output): Internal power MOSFET output switches.
Enable (Input). Logic low will shut down the device, reducing the quiescent
current to less than 4µA.
Voltage scaling pin (input): A low on this pin will scale the output voltage
down to specified level.
Connect to V_OUT to sense output voltage.
Feed Forward Capacitor. Connect a 560pF capacitor.
Analog Ground.
Supply Voltage (Input): Requires bypass capacitor to GND.
Power Ground.
