输出到输入电压
差的限制以这种方式放电高达μ的输出电容器不会损坏器件因为电流会迅速衰减但是应避免连续反向电流当引脚低时可防止这种情况内部 元件具有固有的寄生二极管在正常操作期间输入电压高于输出电压并且寄生二极管被反向偏置然而当低于控制电路有效的值或者引脚低（仅限）并且输出电压高于输入电压 （典型值）时寄生二极管变为正向偏置电流从输出引脚通过二极管流向输入引脚寄生二极管中的电流应限制在一个连续的峰值如果在双电源系统中使用其中调节器输出负载返回到负电源则输出引脚必须二极管钳位接地以限制负电压过渡此保护钳建议使用肖特基二极管

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
