NOTE 1: OUT may be shorted to GND for 1 sec without damage only if the input supply is limited to less
than 200mA, but shorting OUT to V
+
may damage the device and should be avoided. Also, for
temperatures above +85°C, OUT must not be shorted to GND or V
+
, even instantaneously, or
device damage may result.
Stresses beyond those listed under “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 for extended periods may affect device reliability.
