Pin Function

Regulated Output.

Sense (Input): Output-voltage sensing end of internal voltage divider for fixed 5V

operation. Not used in adjustable configuration.

Shutdown/Enable (Input): TTL compatible input. High = shutdown, low or open

= enable.

Ground.

Error Flag (Output): Active low, open-collector output (low = error, floating =

normal).

3.3V/4.85/5V Tap: Output of internal voltage divider when the regulator is

configured for fixed operation. Not used in adjustable configuration.

Feedback (Input): 1.235V feedback from internal voltage divider’s TAP (for fixed

operation) or external resistor network (adjustable configuration).

Unregulated Supply Input.
