GND (Pin 1, 7): Ground. These pins should be tied to a

groundplaneforbestperformance.Theexposedpadmust

be soldered to PCB ground to provide electrical contact

and optimum thermal performance.

VIN (Pin 2): Input Supply Voltage. VIN should be bypassed

with a 1µF to 4.7µF low ESR ceramic capacitor.

VOUT (Pin 3): Regulated Output Voltage. VOUT should be

bypassed with a low ESR ceramic capacitor providing at

least 2µF of capacitance as close to the pin as possible

for best performance.

C+ (Pin 4): Flying Capacitor Positive Terminal.

C– (Pin 5): Flying Capacitor Negative Terminal.
