Pinout and package

Package8-Lead MSOP

Pin	Name	Function
1	OUT	(Output): Supplies power to the load. A minimum output capacitor of 3.3µF is required to prevent oscillations.
2	SENSE	(Sense): Input to the error amplifier for fixed voltage versions. Connect to the load for optimum regulation.
3	BYP	(Bypass): Connection point for bypass capacitor to lower output noise and improve transient response.
4	GND	(Ground): Ground pin.
5	SHDN	(Shutdown): Shutdown control pin, active low.
6	IN	(Input): Input voltage pin.
