FB/SET
LDO Regulator Output Set. Feedback for V
REG
adjustment (V
FB
> 200mV).
Connect FB/SET to GND for a fixed 10V output REG. Connect FB/SET to a
resistor ladder to set V
REG
.

CC
Power-Supply Input. Bypass to GND with a low-ESR ceramic capacitor of
1µF. Input of the internal housekeeping regulator and of the main REG
regulator.

DRV
Output Driver Supply Voltage. Decouple DRV with a low ESR > 0.1µF
ceramic capacitor to PGND placed in close proximity to the device. DRV
can be powered independently from REG. Connect DRV, REG, and V
CC
together when there is no need for special DRV supply sequencing and
the power-MOSFET gate voltage does not need to be regulated or limited.

REG
Voltage Regulator Output. Connect to DRV for driving the power MOSFET
with regulated V
GS
amplitude. Bypass with a low-ESR 1µF (minimum)
ceramic capacitor to GND placed in close proximity to the device to
ensure regulator stability.

EP
Exposed Pad. Internally connected to GND. Connect to GND plane or
thermal pad and use multiple vias to a solid copper area on the bottom of
the PCB.
