Adjustable LM317 Power Supply

We have a new article today on the REUK.co.uk website which will hopefully answer a common question we receive on how to make a LM317 Adjustable Power Supply.

High current adjustable power supply with LM317 and parallel connected power transistors

Pictured above is the high current version where the 1.5A current limit of the LM317 is overcome with the addition of one or more NPN power transistors (2N3055 in this example).
