linear regulator supply

This electronic circuit is power supply that is a compact, easy to build and use positive variable power supply module. It is ideal for powering any application requiring a DC supply at current levels up to 1.5A.
Diodes D1-4 form a bridge rectifier which converts the AC input voltage into a DC level. They also allow [...]

The LM138 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 5A over a 1.2V to 32V output range. They are exceptionally easy to use and require only 2 resistors to set the output voltage. Careful circuit design has resulted in outstanding load and line regulation—comparable to many commercial power [...]

Here is stabilised power supply with short circuit protection. It’s an efficient 4-stage stabilized power supply unit for testing electronic circuits; and it provides well regulated and stabilized output, which is essential for most electronic circuits to give proper results. The circuit provides an audio- visual indication if there is a short circuit in the [...]
