QFN-24 (4mmx4mm)

………...42….....9..…°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,

JA, 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 cause excessive die temperature, and the

regulator may 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.
