(2)

Continuous Power Dissipation (T_A= +25°C)

SOIC8E...................................................... 2.5W

QFN10 (3 x 3 mm) ..................................... 2.5W

Junction Temperature...............................150°C

Lead Temperature ....................................260°C

Storage Temperature.............. –50°C to +150°C

Notes:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature T_J(MAX), the junction-to-

ambient thermal resistance θ_JA, and the ambient temperature

T_A. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by P_D(MAX) = (T_J

(MAX)-T_A)/θ_JA. 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) The device is not guaranteed to function outside of its

operating conditions.

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