Variable Dc Regulated Power Supply Circuit Diagram. This is variable dc power supply circuit or we can call it adjustable dc power supply which give us a 1 2v 25v output voltage. One of them is the extra pair of 470 uf capacitor and 1n4007 diodes below the main bridge rectifier.
Variable power supply circuit. For smaller voltages we normally use batteries as a reliable source. The ic is capable of delivering up to 1a of output current.
The block diagram of a regulated power supply mainly includes a step down transformer a rectifier a dc filter and a regulator.
It is actually very similar to most of the lm317 based power supply with some key difference. One of them is the extra pair of 470 uf capacitor and 1n4007 diodes below the main bridge rectifier. It is actually very similar to most of the lm317 based power supply with some key difference. Regulated power supply circuit block diagram of regulated power supply.
