11 Power Supply Recommendations
When using TL43xLI as a Linear Regulator to supply a load, designers typically use a bypass capacitor on the
output/cathode pin. When doing this, be sure that the capacitance is within the stability criteria shown in
Figure 13.
In order to not exceed the maximum cathode current, be sure that the supply voltage is current limited. Also, be
sure to limit the current being driven into the Ref pin, as not to exceed it's absolute maximum rating.
For applications shunting high currents, pay attention to the cathode and anode trace lengths, adjusting the width
of the traces to have the proper current density.
12 Layout
12.1 Layout Guidelines
Bypass capacitors should be placed as close to the part as possible. Current-carrying traces need to have widths
appropriate for the amount of current they are carrying; in the case of the TL43xLIx, these currents are low.
