Note 8.
Package thermal resistance indicates the ability of the package to dissipate heat generated on the die. Given ambient temperature and power dissipation,
the thermal resistance parameter can be used to determine the approximate operating junction temperature. Operating junction temperature directly effects
product performance and reliability.
Note 9.
This part specifically does not have thermal shutdown protection to avoid safety problems related to an unintentional restart due to thermal time constant
variations. Care should be taken to prevent excessive power dissipation on the die.
