Variable stabilizer power supply / Ahmad Najme Baharom

The course KEU280 is designed primary to help student’s to get the experience in learning basic practical and construct a electronic project and also study skill in their preparation for life. In addition, all students in semester 5 are compulsory to take the course KEU380 next semester.
The project 1 in the booklet preparing how to construct and knowing how the circuit is work also the theoretical and information background, which more complete and sophisticate method of research and development.
This project 1 (KEU280) is prepared into several sections. Each section presents a detailed description of the components and circuit. It is also consists objectives of the project, work plan and conclusion at the end of the project.
This circuit operates to convert 24V DC to variable voltage from 30V down to 3V and stabilized the voltage. IC LM723 was used to stabilize the voltage. These circuits that can be apply to solve most power supply problems arising in the everyday work of any electronics workshop
