Pin Function
Feedback (Input): Output voltage feedback to regulator. Connect to output
of supply for fixed versions. Connect to 1.23V tap of resistive divider for
adjustable versions.
Signal Ground.
Shutdown (Input): Logic low enables regulator. Logic high (> 2.4V) shuts
down regulator.
Power Ground.
Supply Voltage (Input): Unregulated +4V to +24V supply voltage.
Switch (Output): Emitter of NPN output switch. Connect to external storage
inductor and Shottky diode.
Not internally connected. Solder to printed circuit for maximum heat transfer.
