PIN			TYPE	DESCRIPTION
NAME	FIXED	ADJUSTABLE	TYPE	DESCRIPTION
FB	—	1	I	In the adjustable configuration, this pin sets the output voltage with the help of the feedback divider.
GND	2	2	—	Ground pin.
IN	4	4	I	Input supply pin. A capacitor with a value of 0.1 µF or larger is recommended from this pin to ground. See the Section 8.2.1.3 section for more information.
NC	1, 3	3	—	No connect pin. This pin is not connected internally. Connect this pin to ground for best thermal performance or leave floating.
OUT	5	5	O	Output of the regulator. A capacitor with a value of 1 µF or larger is required from this pin to ground.⁽¹⁾ See the Section 8.2.1.3 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.
