Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of
themaximum junction temperature TJ (MAX), the junction-
toambient
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.
3) Measured on JESD51-7， 4-layer PCB.
