Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of
the maximum junction temperature T
J
(MAX), the 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 damage. Thermal shutdown
