Symbol
Function
Regulator Enable Control Input. Drive RUN above 1.5V
to turn on the part. Drive RUN below 0.3V to turn it off.
RUN/EN
In shutdown, all functions are disabled drawing <1KA
supply current. Do not leave RUN floating.
GND Ground
Power Switch Output. It is the Switch note connection to
SW external Inductor. This pin connects to the drains of the
internal P-CH and N-CH MOSFET switches.
Supply Input Pin. Must be closely decoupled to GND,
VIN
Pin 2, with a 2.2µF or greater ceramic capacitor.
VFB (ADJ): Feedback Input Pin. Connect FB to the
center point of the external resistor divider.
The feedback threshold voltage is 0.6V.
VFB/VOUT
VOUT (Fixed): Output Voltage Pin.
An internal resistive divider divides the output voltage
down for comparison to the internal reference voltage.
