Actually Resistor and capacitor is added as RC circuit

Actually MEM_3V3_EN is just a signal name. It is not connected to anywhere. Only NVCC_3V3 power rail has role on the EN pin. So value of C52 is OK..right?

Could you please elaborate below comment.The capacitor C52 can also perhaps be reduced to 10nF or omitted. If the signal MEM_3V3_EN is controlled by another device, the discharge current from C52 may become too high.

I didnt saw any problem. So I send schematics to you to check and confirm.
