Power supply input. A low ESR input capacitance should be located as close as possible to the VIN
pin and exposed pad (EP).
Active high enable input for the device.
Soft-start control pin. An internal 2 µA current source charges an external capacitor connected between
SS and GND pins to set the output voltage ramp rate during startup. The SS pin can also be used to
configure the tracking feature.
Power ground and signal ground. Provide a direct connection to the EP. Place the bottom feedback
resistor as close as possible to GND and FB pin.
Feedback pin. This is the inverting input of the error amplifier used for sensing the output voltage. Keep
the copper area of this node small.
