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.
Note 2.
JA
is measured under natural convection (still air) at T
A
= 25C with the component mounted on a high effective-thermal-
conductivity four-layer test board on a JEDEC 51-7 thermal measurement standard.
JC
is measured at the exposed pad
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.
