Sense (Input): Output-sense-voltage end of internal resistive divider.
Connect to OUT (V OUT = 5V) for fixed5V operation; also see TAP.
Not used in adjustable configuration.
Shutdown (Input): Active-low input enables regulator.
(Low = enable; high = shutdown.)
Error Flag (Output): Open collector (active-low) output. Active state
indicates an output (V OUT ) undervoltage condition.
(Low = error, floating = normal.)
Divider Tap (Output): Resistive voltage divider tap. With 5Vapplied to
SNS, VTAP is approximately 1.23V. Connect to FB for 5V operation.
Not used in adjustable configuration.
Feedback (Input): Error amplifier input. Compared to internal1.23V
reference. Connect to external voltage divider for adjustable operation
or internal voltage divider (TAP) for 5V operation (see SNS, TAP).
