Feedback — Internally connected to the regulation, overvoltage, and short-circuit comparators. The

regulation reference point is 0.8 V at this input pin. Connect the feedback resistor divider between the

output and ground to set the output voltage.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
