Notes:

2) Exceeding these ratings may damage the device.

3) 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.

4) L=5mH, Vgs=10V, VDD=1.4V

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

operating conditions.

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