NOTES:

1) Absolute maximum are rated under room temperature unless

otherwise noted. Exceeding these ratings may damage the

device.

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

dissipation produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

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