Notes:

1) Exceeding these ratings may damage the device.

2) 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.

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

operation conditions.

4) Measured on JESD51-7, 4-layer PCB.
