Notes:

1) Exceeding these ratings may damage the device.

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

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

operating conditions.

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