I/O DESCRIPTION
NAME NO.
When connected to GND, this pin adds 0.1 V to the nominal output voltage of the regulator.
0P1V 12 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 0.2 V to the nominal output voltage of the regulator.
0P2V 11 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 0.4 V to the nominal output voltage of the regulator.
0P4V 10 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 0.8 V to the nominal output voltage of the regulator.
0P8V 9 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 1.6 V to the nominal output voltage of the regulator.
1P6V 8 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 3.2 V to the nominal output voltage of the regulator.
3P2V 6 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 6.4 V to the nominal output voltage of the regulator.
6P4V1 5 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
When connected to GND, this pin adds 6.4 V to the nominal output voltage of the regulator.
6P4V2 4 I
Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.
Enable pin. The device is enabled when the voltage on this pin exceeds the maximum
EN 13 I
enable voltage, V
EN(HI)
. If enable is not required, tie EN to IN.
GND 7 — Ground
Input supply. A capacitor greater than or equal to 1 µF must be tied from this pin to ground to
assure stability.
IN 15, 16 I A 10-µF capacitor is recommended to be connected from IN to GND (as close to the device
as possible) to reduce circuit sensitivity to printed circuit board (PCB) layout, especially when
long input traces or high source impedances are encountered.
NC 2, 17-19 — This pin can be left open or tied to any voltage between GND and IN.
Noise reduction pin. When a capacitor is connected from this pin to GND, RMS noise can be
reduced to very low levels. A capacitor greater than or equal to 10 nF must be tied from this
NR 14 —
pin to ground to assure stability. A 1-µF capacitor is recommended to be connected from NR
to GND (as close to the device as possible) to maximize ac performance and minimize noise.
