Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
Lead Temperature (soldering, 10s) (Note 2) ...................+300°C
Note 1:
Thermal properties are specified with product mounted on PC board with one square-inch of copper area and still air. With
minimal copper, the SOT23 package dissipates 712mW at +70°C. With a quarter square inch of copper, it will dissipate
790mW at +70°C. Copper should be equally shared between the IN, OUT, and GND pins.
Note 2:
This device is constructed using a unique set of packaging techniques that imposes a limit on the thermal profile to which
the device can be exposed during board-level solder attach and rework. The limit permits only the use of the solder profiles
recommended in the industry standard specification, IPC JEDEC-J-STD-020A, paragraph 7.6, Table 3 for the IR/VPR and
convection reflow. Preheating is required. Hand or wave soldering is not allowed.
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.
