Pin Function
Regulated Output.
Sense (Input): Output-voltage sensing end of internal voltage divider for ï¬xed 5V
operation. Not used in adjustable conï¬guration.
Shutdown/Enable (Input): TTL compatible input. High = shutdown, low or open
= enable.
Ground.
Error Flag (Output): Active low, open-collector output (low = error, ï¬oating =
normal).
3.3V/4.85/5V Tap: Output of internal voltage divider when the regulator is
conï¬gured for ï¬xed operation. Not used in adjustable conï¬guration.
Feedback (Input): 1.235V feedback from internal voltage dividerâs TAP (for ï¬xed
operation) or external resistor network (adjustable conï¬guration).
Unregulated Supply Input.
