QFN-14 (3x4mm) .…….. ……..48 ..... 11... °C/W

NOTES:

1) Exceeding these ratings may damage the device.

2) For details on EN/SYNC’s ABS MAX rating, please refer to

the EN/SYNC control section on page 15,.

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 produce 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 5.5V absolute

maximum value at any input condition.

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