輸出到輸入電壓
差的限制以這種方式放電高達μ的輸出電容器不會損壞器件因為電流會迅速衰減但是應避免連續反向電流當引腳低時可防止這種情況內部 元件具有固有的寄生二極管在正常操作期間輸入電壓高于輸出電壓并且寄生二極管被反向偏置然而當低于控制電路有效的值或者引腳低（僅限）并且輸出電壓高于輸入電壓 （典型值）時寄生二極管變為正向偏置電流從輸出引腳通過二極管流向輸入引腳寄生二極管中的電流應限制在一個連續的峰值如果在雙電源系統中使用其中調節器輸出負載返回到負電源則輸出引腳必須二極管鉗位接地以限制負電壓過渡此保護鉗建議使用肖特基二極管

Output to input voltage
Poor limits discharge in this way up to μ The output capacitor will not damage the device because the current will decay rapidly, but continuous reverse current should be avoided. This can be prevented when the pin is low. The internal components have inherent parasitic diodes. During normal operation, the input voltage is higher than the output voltage and the parasitic diodes are reverse biased. However, when it is lower than the effective value of the control circuit or the pin is low (only) and the output voltage is higher than the input voltage (typical value) When the parasitic diode becomes a positive bias current, the current flowing from the output pin through the diode to the input pin in the parasitic diode should be limited to a continuous peak. If the output load of the regulator returns to the negative power supply in a dual power supply system, the output pin must be grounded by the diode clamp to limit the negative voltage transition. This protective clamp is recommended to use Schottky diodes
