Pin Function
Supply Input
Ground: MSOP-8 pins 5 through 8 are internally connected.
Regulator Output
Enable (Input): CMOS compatible control 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): Feedback input. Connect to resistive voltage-divider network.
