Power Supply circuits diagram electronics projects

This solar panel stabilizer circuit is designed using a FET transistor, an LM317 voltage regulator and some other common electronic components.

This 5V switching power supply circuit is made using LM1575 or LM2575 integrated circuit manufactured by National Semiconductor.

A very simple 5-20V fixed output power supply circuit, which requires very few electronic components and has a very low voltage drop and may provide a maximum output current of 1 A, and reverse voltage protection and peaks of up to 60 V, can be made using this circuit diagram.
This 5-20V fixed output power supply circuit is built using LM2941C integrated circuit manufactured by National Semiconductor.
In circuit, C1 is necessary only if the distance is relatively large filter capacitor.
Output circuit was designed to be stabilized between 5 V and 20 V.
