Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum

junction

temperature

(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. Thermal shutdown engages at TJ=150

oC(TYP) and

disengages at TJ=130

oC(TYP)

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

operating conditions.

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