Notes:

1) Exceeding these ratings may damage the device.

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

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

operating conditions.

4) Measured on approximately 1” square of 1 oz copper.
