Note 1.

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

ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the

operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions may affect

device reliability.

of the package.

Note 3. Devices are ESD sensitive. Handling precaution is recommended.

Note 4. The device is not guaranteed to function outside its operating conditions.

Note 5. GATE to OUT voltage is internally generated and clamped. External driving at GATE pin is forbidden because it may

damage the device.

Note 6. All currents into device pins are positive, all currents out of device pins are negative. All voltages are referenced to GND

unless otherwise specified.
