Notes:

1) Exceeding these ratings may damage the device.

2) Please refer to

the “Enable/SYNC” control section on page 15

for the absolute maximum rating of EN.

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

ambient thermal resistance θ

dissipation produces an excessive die temperature, causing

the regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

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

operating conditions.

5) The output voltage CANNOT exceed the 5.2V absolute

maximum value at any input condition.

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