Pin Function
Enable (Input): CMOS-compatible control input. Logic high = enable, logic
low or open = shutdown.
Supply (Input)
Regulator Output
Flag (Output): Open-collector error flag output. Active low = output under-
voltage.
Adjustment Input: Feedback input. Connect to resitive voltage-divider
network.
