Pin Name Pin Function
2 (fixed) — FLG
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.
2 (adj) — ADJ Adjustable Feedback Input: Connect to voltage divider network.
3 1 IN Power Supply Input.
4 3 OUT Regulated Output.
1 — EN Enable (input): Logic low = shutdown; logic high = enabled.
5–8 2 GND
Ground: Pins 5, 6, 7, and 8 are internally connected in common via the
leadframe.
