8 Application Notes
☆  The electronic inspecton point should be kept as close as possible at the root of the pin;
☆  It is strictly forbidden to bend the pins;
☆  To prevent the application of two or more absolute maximum ratings on the device at the same time;
☆  To prevent the device from falling off;
☆  To prevent the output and ground short circuit;
☆  To prevent the device from being reversed or dislocated;
☆  During assembly, the bottom of the product should be attached as close as possible to the circuit board to avoid damage to the pin, take shockproof measures for necessary ;
☆  Focus on device power consumption, the power consumption ,When the input/output voltage difference(VIN-VOUT) is large, output current IO should be smaller;When the input/output voltage difference(VIN-VOUT)is small ,output current IO should be larger; When the device power consumption is large, be sure to configure the appropriate heat sink to prevent the device damaged due to overheating or into the overheating protection status;
☆  Both positive and negative terminals of power supply shall be correctly connected when power is applied so as to avoid permanent damage to the device.;
☆ Anti-static measures should be taken during storage and transportation.
