5.1
Integrated thermal protection circuitry shuts the
regulator off when die temperature exceeds 160°C.
The regulator remains off until the die temperature
drops to approximately 150°C.
5.2
The amount of power the regulator dissipates is
primarily a function of input voltage, output voltage and
output current. The following equation is used to
calculate worst case actual power dissipation:

Maximum allowable power dissipation:
In this example, the TC1054 dissipates a maximum of
20.7 mW; below the allowable limit of 318 mW. In a
similar manner,
used to calculate maximum current and/or input
voltage limits.
5.3
The primary path of heat conduction out of the package
is via the package leads. Therefore, layouts having a
ground plane, wide traces at the pads and wide power
supply bus lines combine to lower θ
increase the maximum allowable power dissipation
limit.
