Notes:

2)

Exceeding these ratings may damage the device.

3)

Repetitive rating: Pulse width = 100µs, duty cycle limited by

maximum junction temperature.

4)

TA = +25°C. 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 produces an excessive die

temperature, causing the regulator to go into thermal

shutdown. Internal thermal shutdown circuitry protects the

device from permanent damage.

5)

The device is not guaranteed to function outside of its

operating conditions.

6)

Measured on JESD51-7, 4-layer PCB.
