Please advise proper filtring. Noise develops not only at output (ripple voltage), but also at input (ripple current). At least use a 100nF X7R directly at input and output to ground. If your application is more sensitive to noise you could provide a pi-filter at input and output, consisting of two tantals each and a suitably low series resistance (voltage drop), eventually added by a small soft ferrite choke. This measure eliminates the noise at the source and keeps the rest circuitry almost noisefree, rather important when dealing with analog electronics, for instance. Kai |
