Part Number:TPS7A49
The datasheet of the LDO TPS7a49 specifies a limit of -36 ... 0.3V for the OUT pin to IN pin voltage. I am using the regulator with a relatively large output capacitance of 1mF and when I turn off the IN voltage of the LDO (EN is connected to IN), said limit is not met because the output capacitance discharges slower than the input net. I can see the same behaviour on the evaluation module TPS7A30-49EVM-567 after disconnecting the input voltage.
Can this behaviour destroy the regulator?
Are there any countermeasures that could be taken?
