Maximum and Minimum voltage fluctuation for 5v power supply

[sridharreddy]

hi,

can any one know; what will the maximum and minimum variation(or fluctuation) of voltage around a nominal value of a 5v power supply?

thanks,
sridhar

it depends on sensitivity of the system for which you are using the supply. however +-0.5V are Tolerable.

Check the devices in the circuit you are using. Some will manage a wide range, some 10%, but some will only tolerate 5%. If it is an analog design then you might need to do a fair amount of circuit analysis to decide.
