3.3V and 5V Constant Voltage Regulators Circuits. DIY

Circuit diagrams for making 3.3V and 5V constant voltage regulators.

Capacitors used in regulator circuits are necessary for the voltage to be stable. At the same time, capacitors filter out noise. And they should be placed as close as possible to the regulators IC.
