LP2950: Reverse Input-Output Voltage

Part Number: LP2950

Dear Specialists,

My customer is considering LP2950 and has a question.

I would be grateful if you could advise.


LP2950 is PNP voltage ragulator.

In this device, is there a parasitic diode from output to input.

Also is it necessary to add an external diode when considering the reverse current from the output to the input?

In this case, input cap is 1uF and output cap is 1uF.

For example, LP2985 has a parasitic diode inside and external diode is needed.

Is it similar to LP2950?


I appreciate your great help in advance.

Best regards,
