PIN I/O(1) DESCRIPTION
NAME NO.
EN 13 I Enable. This dual-polarity pin turns the regulator on when |VEN| ≥ 2 V. The EN pin can be connected to IN if not used. If VEN is negative polarity, then keep |VEN| ≤ |VIN|.
FB 3 I Feedback. This pin is the input to the control-loop error amplifier. It is used to set the output voltage of the device and is normally equal to VREF (–1.182 V, typical) during operation.
GND 7 — Ground.
IN 15, 16 I Input supply. It is recommended to connect a 10-µF capacitor from IN to GND (as close to the device as possible).
NC 2, 4–6, 8–12, 17–19 — No connect. This pin is not internally connected. It is recommended to connect these pins to GND to prevent charge buildup; however, these pins can also be left open or tied to any voltage between GND and VIN.
NR_SS 14 — Noise reduction and soft start. A capacitor connected from this pin to GND controls the soft-start function and allows RMS noise to be reduced to very low levels. TI recommends connecting a 100-nF capacitor from NR_SS to GND (as close to the device as possible) to filter the noise generated by the internal band gap and maximize AC performance.
OUT 1, 20 O Output of the regulator. A capacitor greater than or equal to 10 µF must be tied from this pin to ground to ensure stability. TI recommends connecting a 47-µF ceramic capacitor from OUT to GND (as close to the device as possible) to maximize AC performance.
Thermal
Pad		 — — Connect the thermal pad to a large-area ground plane. The thermal pad is not internally grounded and it must be externally tied to GND for proper operation.
