> 3.3 | Linear and Capacitor Supply

> In a mixed power supply solution there are two components that can supply the current for the module if operated in parallel. These components are usually a big capacitor and a power supply circuit. Such a combination is the most easy and cheapest to realize. Most power supply circuits require a capacitor at the output side in any case.

> With this solution power is supplied from both the capacitor and the IC.
