Fault Conditions
A Fault condition occurs if VREF falls below 4.65V. When a
Fault is detected, OUT is disabled. When VREF exceeds
4.80V, the Fault condition clears, and OUT is enabled.
Ground Plane Requirements
Careful layout is essential for satisfactory operation of the
device. A good ground plane must be employed. A unique
section of the ground plane must be designated for high di/dt
currents associated with the output stage. V DD should be
bypassed directly to GND with good high frequency capacitors.
