EN to GND Voltage

------------------------------------------------------------------------------------------------------- 7V

EN to Input Voltage ---------------------------------------------------------------------------------------------------------- +0.3V

Output current --------------------------------------------------------------------------------------------------------------- 350mA

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

These are stress ratings only, and function operation of the device at these or any other conditions beyond

those

indicated

under

“recommended

operating

conditions”

is

not

implied.

Exposure

to

absolute-maximum-rated conditions for extended periods may affect device reliability.
