Goes low when VOUT drops by 6% of its ERROR — 5 O nominal value. Determines the output voltage. Connect to VTAP (with OUTPUT tied to SENSE) FEEDBACK — 7 I to output the fixed voltage corresponding to the part version, or connect to a resistor divider to adjust the output voltage. GND 2 4 — Ground INPUT 3 8 I Supply input OUTPUT 1 1 O Voltage output. Senses the output voltage. Connect to OUTPUT (with FEEDBACK tied to VTAP) SENSE — 2 I to output the voltage corresponding to the part version. SHUTDOWN — 3 I Active-high input. Shuts down the device. VTAP — 6 O Tie to FEEDBACK to output the fixed voltage corresponding to the part version.
