Notes:

2) Exceeding these ratings may damage the device.

3) 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.

4) The device is not guaranteed to function outside of its

operating conditions.

5) Measured on JESD51-7 4-layer board.
