Notes:

1) Absolute maximum ratings are rated under room temperature

unless otherwise noted. 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,

θ

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 will cause excessive die temperature, and the

module will go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

3) This device is not guaranteed to function outside its operating

conditions.

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

5) Measured on MPS standard EVB: 8.9cmx8.9cm, 2oz. copper,

4-layer PCB.
