Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum
junction
temperature
TJ
(MAX),
the
junction-to-ambient thermal resistance θJA, and the ambient
temperature TA. The maximum allowable continuous power
dissipation at any ambient temperature is calculated by PD
(MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable
power dissipation will cause excessive die temperature, and
the regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage. Thermal shutdown engages at TJ=150
oC(TYP) and
disengages at TJ=130
oC(TYP)
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4-layer board.
