POK
EN
Enable Input. Pulling this pin below 0.4V turns the regulator off.
Do not float.
Power Input. This pin is the drain input to the power device that supply current
to output pin.
IN
Supply Input for Internal Circuit. Input Bias Voltage for powering all circuitry on
the regulator except the output power TR.
BIAS
SS
Soft-Start Pin. Connect a capacitor between this pin and the ground to
determine the soft-start time. If soft-start is not needed, the SS pin can be left
floating. (Do not connect to ground directly.)
OUT
FB
Power Output. This pin is power output of the device.
Feedback Voltage. A resistor divider from the output to GND is used to set the
regulation voltage as VOUT= 0.6V x (1+R2/R1)
GND
Ground
Thermal Exposed
PAD
Connect to Ground.
