I

When connected to GND, this pin adds 0.1 V to the nominal output voltage of the regulator.

Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.

0P2V

11

I

When connected to GND, this pin adds 0.2 V to the nominal output voltage of the regulator.

Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.

0P4V

10

I

When connected to GND, this pin adds 0.4 V to the nominal output voltage of the regulator.

Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.

0P8V

9

I

When connected to GND, this pin adds 0.8 V to the nominal output voltage of the regulator.

Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.

1P6V

8

I

When connected to GND, this pin adds 1.6 V to the nominal output voltage of the regulator.

Do not connect any voltage other than GND to this pin. If not used, leave this pin floating.

3P2V

6

I

I

Input supply. A capacitor greater than or equal to 1 µF must be tied from this pin to ground to

assure stability.

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.

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

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.
