Hi,
I have been desiging a circuit for which customer is providing 5V regulated VCC to operate. As a general practice we put a bulk capacitor at VCC input line. I had been thinking it is mostly matter of experiance and we placed a capacitor around 10uF as consider on previous design.
Now our customer asked to justify this value and I am not sure how to calculate the value of bulk capacitors for such application (If I would use a LDO on board then simply I would refer the data sheet which suggest some values, but fortunatly this is not the case). My application is drawing a DC current from supply.
I would appreciate if any one can help me regarding this.
Thanks
Umesh.
