Pin Function
Supply Voltage (Input): Unregulated +4V to +40V supply voltage.
Switch (Output): Emitter of NPN output switch. Connect to external storage
inductor and Shottky diode.
Ground.
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.
Shutdown (Input): Logic low enables regulator. Logic high (> 2.4V) shuts down
regulator.
