Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
(MAX),
the
maximum
junction
temperature
T
J
junction-to-ambient thermal resistance
θ
JA
, and the ambient
temperature T
A
. The maximum allowable continuous power
dissipation at any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. 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
o
damage. Thermal shutdown engages at T
J
=150 C(TYP) and
o
disengages at T
J
=130 C(TYP)
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7 4-layer board.
