Basic Power Supply Module

This is a basic power supply in a box using two 7805 regulators, with a couple of nice twists. Input (7VAC to 20VAC) or (7VDC to 30VDC) (Transformer/Power Pack available separately). Two regulated outputs are provided - one fixed at +5V, the other variable from +5V up. The upper limit for the second voltage is the input voltage less 3V. The circuit is simple and the regulators can be exchanged for other types. This makes a good starting point for experimenting with different of linear regulator topologies. A good introduction to three-terminal linear voltage regulators.
