Pin Function
Supply Input.
Ground: SOT-223 pin 2 and TAB are internally connected. SO-8
pins 5 through 8 are internally connected.
Regulator Output. Pins 3 and 4 must be tied together.
Enable (Input): CMOS compatible control input. Logic high =
enable; logic low = shutdown.
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): Feedback input. Connect to resistive voltage-divider
network.
