F or greater ceramic capacitor.
Analog supply input pin. Provides bias for internal circuitry.
Analog ground pin
FB pin (AAT1153IDE-0.6): Adjustable version feedback input. Connect FB to the center point of the
external resistor divider. The feedback threshold voltage is 0.6V.
OUT pin (AAT1153IDE-1.8): Fixed version feedback input. Connect OUT to the output voltage, VOUT.
Switching node pin. Connect the output inductor to this pin.
Power ground pin
Power ground exposed pad. Must be connected to bare copper ground plane.
