Pin Function
Error FLAG (Output): Open-collector output is active low when the output
is out of regulation due to insufficient input voltage or excessive load. An
external pull-up resistor is required.
Adjustable Feedback Input: Connect to voltage divider network.
Power Supply Input.
Regulated Output.
Enable (input): Logic low = shutdown; logic high = enabled.
Ground: Pins 5, 6, 7, and 8 are internally connected in common via the
leadframe.
