Function
Current Sense. Connected to the more
negative terminal of the sense resistor as
well as the Power MOSFET’s source pin.
IS must be tied to VIN pin if the current
limit feature is not used.
No Connect.
Gate Drive for the external MOSFET.
Input Voltage. This is also the positive
terminal connection of the current sense
resistor.
Output Voltage Sense. This pin is
connected to the MOSFET’s drain and
directly to the load for optimal load regula-
tion. Bypass to ground with a 10 µF or
larger capacitor.
Device Ground. This pin should be tied to
system ground closest to the load.
Enable. Pulling this pin to a logic High or
tying the pin to the input voltage will enable
the output. Pulling this pin low will disable
the regulator output.
