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.
