TQFN8 (3mm x 3mm) ............48 ...... 11 ...

°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 will cause excessive die

temperature, and the regulator will go into thermal

shutdown. Internal thermal shutdown circuitry protects the

device from permanent damage. Thermal shutdown

engages

TJ=150

oC(TYP)

and

disengages

TJ=130

oC(TYP)

3) The device is not guaranteed to function outside of its

operating conditions.

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