Enable/Shutdown (Input): CMOS compatible input. Logic high = enable,
logic low or open = shutdown. Do not leave floating.
Reference Bypass: Connect external 470pF capacitor to GND to reduce output
noise. May be left open. For 1.8V or 2.5V operation, see “Applications
Information.”
Adjust (Input): Adjustable regulator feedback input. Connect to resistor voltage
divider.
