Dual Power Supply with 48V Phantom Power Output

Posted December 27th, 2013 by

Presented is another power supply schematic, but this time using adjustable regulators instead of the normal 78xx and 79xx series fixed voltage regulators. These typically provide lower noise output, and the output voltages can be changed by altering the values of resistors, rather than replacing the three-terminal regulators (which can be quite cumbersome).

Regulated Dual Power Supply

Posted December 1st, 2013 by

The first project I’ve decided to publish here is a simple dual power supply, which I use for powering audio circuits requiring such a supply. It’s pretty much a standard design, and should be suitable for low power devices (ie. don’t use it for a power amplifier or a toaster or anything).
