Default Discussion: Linear regulator=low-cost dc/dc converter

Quote:
Susanne Nell EDN The circuit in Figure 1 is a good choice if you need a power supply with high efficiency and you don't want to use expensive dc/dc-converter ICs. The heart of the circuit is IC1, the common, inexpensive LM7805 linear regulator.

of course, it will work. only here we have used the principle of determining the stabilized voltage using a comparator. therefore, the presence of ripple in voltage is fundamentally stable
