Function
Enable pin. Active high. In shutdown, all functions are disabled drawing <1µA supply current.
Do not leave EN floating.
Ground pin.
Switching node. Connect the output inductor to this pin. Connects to the drains of the internal
P- and N-channel MOSFET switches.
Supply input pin. Must be closely decoupled to GND with a 2.2µF or larger ceramic capacitor.
FB (AAT1106ICB-0.6): Feedback input pin. Connect FB to the center point of the external
resistor divider. The feedback threshold voltage is 0.6V.
OUT (AAT1106ICB-1.5, AAT1106ICB-1.8): Output voltage pin.
