Pin Function
Supply Input
Ground
Enable/Shutdown (Input): CMOS compatible input. Logic high = enable,
logic low or open = shutdown.
Reference Bypass: Connect external 470pF capacitor to GND to reduce
output noise. May be left open.
Adjust (Input): Adjustable regulator feedback input. Connect to resistor
voltage divider.
