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
