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 θJA, and the ambient temperature TA. The

maximum allowable continuous power dissipation at any

ambient temperature is calculated by PD(MAX)=(TJ(MAX)-TA)/θJA.

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.

3) VCC Include AVCC and PVCC, VIN include INP and INN

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