NAME	VSON		WSON		I/O	DESCRIPTION
NAME	FIXED	ADJ.	FIXED	ADJ.	I/O	DESCRIPTION
FB	—	5	—	4	I	In the adjustable configuration, this pin sets the output voltage with the help of the external feedback divider.
GND	4, Pad	4, Pad	3, Pad	3, Pad	—	Ground pin.
IN	1	1	1	1	I	Input supply pin. Use a capacitor with a value of 0.1 µF or larger from this pin to ground. See the Input and Output Capacitor Requirements section for more information.
NC	2, 3, 5, 6, 7	2, 3, 6, 7	2, 4, 5	2, 5	—	No connect pin. This pin is not connected internally. Connect this pin to ground for best thermal performance, or leave floating.
OUT	8	8	6	6	O	Output of the regulator. For the new chip, a capacitor with a value of 1 µF or larger is required from this pin to ground.⁽¹⁾ See the Input and Output Capacitor Requirements section for more information.

(1) The nominal output capacitance must be greater than 0.47 µF. Throughout this document, the nominal derating on these capacitors is 50%. Make sure that the effective capacitance at the pin is greater than 0.47 µF. The legacy chip is stable for any capacitor value ≥ 0.47 μF.
