Analog Ground. P1 must be soldered to the PCB ground.
Supply Voltage Input.
Power Ground. This pin is connected to the internal MOSFET switches. This pin must be
externally connected to AGND.
Enable Input. Logic high enables the chip and logic low disables the chip, reducing the supply
current to less than 1µA. Do not float this pin.
Feedback Input. Adjustable voltage option, connect this pin to the resistor divider.
No Connection Pin.
Switching Node. This pin is connected to the internal MOSFET switches.
Analog Ground. P1 must be soldered to the PCB ground.
