Precautions    V04 During the test, if AC/DC power supply and the ceramic chip capacitors collocation is used, there may be serious voltage spike phenomenon instantaneously. When the power supply access to 16V, the voltage is rushed to about 30V instantaneously. Because of exceeding the limit voltage of chip, the chip is damaged. If you string a small resistance of 1 ohm in the input end during the test, the peak phenomenon can be avoided. In the test, there is serious burr phenomenon only when the AC/DC power is used with ceramic chip capacitors. But electrolytic capacitors and tantalum capacitance won't appear above phenomenon. Please be sure to pay attention to this point when you use AC/DC power. In normal use, when any type of capacitor is used with battery or the supply of fire power, the above phenomenon doesn’t occur. www.microne.com.cn Page 3 of 8 ME6208 Type Characteristics （1）Output CurrentVS.Output Voltage（ Ta = 25 °C） ME6208A50 Output Voltage VS.
