To calculate the maximum allowable power dissipation, assume Tj = 125°C. To ensure that junction temperature
does not exceed the maximum operating rating of 125°C, power dissipation should be verified at the maximum
expected operating frequency, maximum ambient temperature, and minimum and maximum input voltage. The
calculated maximum load current is based on continuous operation and may be exceeded during transient
conditions.
If the power dissipation remains above the maximum allowable level, device temperature will continue to rise.
When the junction temperature exceeds its maximum, the LM26003 engages Thermal Shut Down (TSD). In
TSD, the part remains in a shutdown state until the junction temperature falls to within normal operating limits. At
this point, the device restarts in soft-start mode.
