Notes:

1) Exceeding these ratings may damage the device.

2) About the details of the EN pin’s ABS MAX rating, please

refer to Page 9, Enable section.

3) 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.
