Hello Electronicers,
simple question, I would like to build a 5V regulator with SMD components,
as shown in the picture:
Figure 1. Fixed-Output Regulator

What is the type of capacitors 0.33uf and 0.1 uf I should use?
  • Tantalum Capacitors
  • Aluminum Capacitors
  • Ceramic Capacitors
thank you,
Yursen
 

Hi Yursen,
you can use SMD Aluminum Electrolytic Capacitors.

Any of those options will be fine - go with whatever satisfies your needs for cost/footprint/temperature requirements.
(My order of preference is 1. Ceramic, 2. Tantalum, 3. Electrolytic ... based principally on my irrational dislike of electrolytic caps for reliability/size/HF response reasons :)

I dont think you can find 330nF or 100nF as electrolytic capacitor, these values are to small for this type of capacitor. This should be ceramic or tantal. I personaly use at least 10uF tantal or ceramic on input and 1uF tantal or ceramic on output.
