9 Power Supply Recommendations
Maximum input voltage should be limited to 30 V for proper operation. Place input and output capacitors as close
to the device as possible to take advantage of their high frequency noise filtering properties.
10 Layout
10.1 Layout Guidelines
Make sure that traces on the input and outputs of the device are wide enough to handle the desired currents. For
this device, the output trace will need to be larger in order to accommodate the larger available current.
Place input and output capacitors as close to the device as possible to take advantage of their high frequency
noise filtering properties.
