Pin Function
Feedback (Input): Output voltage sense node. Connect to 1.23V-tap of the
output voltage-divider network.
Ground (Return): Ground.
Current Limit Set (Input): Connect an external resistor to ground to set the
current limit. Do not ground or float this pin.
Shutdown (Input): Logic low (<0.8V) enables regulator. Logic high (>2V) shuts
down regulator.
Supply Voltage (Input): Unregulated +4V to +34V supply voltage.
Switch (Output): Internal power emitter of NPN output switch.
