8 Application Notes of HSK5230 Series Low Voltage Difference Linear DC to DC converter（LDO）

☆ 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.
