Pin Function
Switch (Output): Internal power MOSFET output switches.
Enable (Input): Logic high enables operation of the regulator. Logic low
will shut down the device. Do not leave floating.
Sense: Connect to V
output voltage.
Analog Ground: Connect to central ground point where all high current
paths meet (C
Input Voltage: Connect a capacitor-to-ground to decouple the noise.
Power Ground.
