Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a

function of the maximum junction temperature

allowable continuous power dissipation at any

ambient

temperature

is

calculated

by

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) The device is not guaranteed to function outside of its

operating conditions.
