Thermal Resistance

θJA

θJC

JESD51-7 (5) ............................47 ........... 7°C/W

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 can produce an excessive die

temperature, which may cause 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

the

EV8020-QV-00A,

a

1oz,

2-layer

(63mmx63mm) 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.
