In our previous example, the maximum power dissipa-
tion of the device is calculated under no load and maxi-
mum input supply condition.
The maximum power is calculated using the following
equation:
V

As shown in the power dissipation table, both packages
can handle this power dissipation.
The table below summarizes the maximum power dissi-
pation capability of each package versus ambient tem-
perature.

Stability
The IRU431L has many different domains of stability as
a function of the cathode current. As is typical of three-
terminal shunt regulators, the IRU431L has many do-
mains of stability. The actual domain in which any prac-
tical circuit operates is related to cathode current. In
general the device will be unconditionally stable for any
cathode current if a capacitor, 1
μ
F or larger, is connected
between the cathode and the anode. If the cathode cur-
rent is always higher than 3mA under minimum line and
maximum load conditions, the capacitor value can be
reduced to 0.01
μ
F and the system will be stable.
