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 on

EV8771-Q-00A board at any ambient temperature is

calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the

maximum allowable power 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) The device is not guaranteed to function outside of its

operating conditions.

4) Measured on EV8771-Q-00A, 4-layer PCB.

5) The value of θJA given in this table is only valid for comparison

with other packages and cannot be used for design purposes.

These values were calculated in accordance with JESD51-7,

and simulated on a specified JEDEC board. They do not

represent the performance obtained in an actual application.
