Instructions and Precautions
.
Connect a capacitor of 1000 pF across pins
1
and
2
for external disturbance path.
.
Be careful of the ground line artwork when laying out the printed circuit pattern. Arrange so that the Sg route and load current
flow-in route do not overlap. Refer to the recommended printed circuit pattern or make slits, etc. at pins
2
and
3
.
