Pin Function
Enable (Input): Logic high (≥1.5V) enables regulator. Logic low (≤0.7V)
shuts down regulator. Do not float.
Soft Start Capacitor (External Component): Connect external capacitor to
ground to control the rise time of the output voltage.
Current Limit (External Component): Sets peak current limit of the internal
power MOSFET using an external resistor.
Power Ground (Return): Internal power MOSFET source.
Switch Node (Input): Internal power MOSFET drain.
Supply (Input): +2.4V to +16V for internal circuitry.
Feedback (Input): Output voltage sense node.
Small Signal Ground (Return): Ground
