Current Limit and Thermal Shutdown
shutdown to protect the device during fault conditions. If the
device detects a current limit or short circuit condition,
typically 730 mA, the device limits the drive to the internal
regulator. Thermal shutdown protects the internal circuitry
in the event that maximum junction temperature is
exceeded. When activated, typically at 170 C, the output is
disabled. There is no hysteresis built into the thermal

output will appear to be oscillating. This feature is provided
to prevent catastrophic failures from accidental device
overheating. It is not intended to be used as a substitute
for proper heatsinking.
provided in the maximum ratings table will vary depending
on pad size, adjacent components and air flow. If you are
planning to operate the device close to its maximum junction
temperature it is recommended that you measure the device
temperature in your application to insure junction
temperature is not exceeded.
