Pin Function
Sense: Connect to V_OUT as close to output capacitor as possible to sense
output voltage.
Not internally connected.
Feedback: Connect resistor divider at this node to set output voltage. Resistors
should be selected based on a nominal V_FB = 0.62V.
Enable: Logic high enables operation of the regulator. Logic low will shut down
the device. Do not leave floating.
Switch: Internal power MOSFET output switches.
Output Voltage: The output of the regulator. Connect to SNS pin. For adjustable
option, connect to feedback resistor network.
Power Ground.
Analog Ground.
Input Voltage: Connect a capacitor to ground to decouple the noise.
Connect to PGND or AGND.
