DESCRIPTION
Active-low open-collector error output. Goes low when V_OUT drops by 6% of its
nominal value.
Determines the output voltage. Connect to V_TAP (with OUTPUT tied to SENSE)
to output the fixed voltage corresponding to the part version, or connect to a
resistor divider to adjust the output voltage.
Ground
Supply input
Voltage output.
Senses the output voltage. Connect to OUTPUT (with FEEDBACK tied to V_TAP)
to output the voltage corresponding to the part version.
Active-high input. Shuts down the device.
Tie to FEEDBACK to output the fixed voltage corresponding to the part version.
