Notes:

1) Exceeding these ratings may damage the device..

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

maximum junction temperature TJ(MAX) ， the junction-to-

ambient thermal resistance

JA，and the ambient temperature

TA, the maximum allowable power dissipation at any ambient

temperature is calculated using: PD(MAX)=(TJ(MAX)-TA)/ JA.

Exceeding the maximum 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.

Reduce 0.2 Watts for every 10

oC ambient temperature
