Notes:

1) Exceeding these ratings may cause permanent damage to

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) Devices

are

ESD

sensitive.

Handling

precaution

recommended.

4) The device is not guaranteed to function outside its operating

conditions.

5) Measured on JESD51-7 4-layer board.
