Notes:

1) Exceeding these ratings may damage the device.

2)

The maximum allowable power dissipation is a function

of the

toambient

thermal

resistance

and

the

ambient

dissipation at any ambient temperature is calculated by

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.
