1.2-30V/1.5A variable regulated power supply
This is a simple, but low-ripple powersupply
Power supply 20v-2a
A standard LM723 Voltage Regulator and some darlington pass transitors. In order to reduce the dissipated power, a transformer with two secondary windings is needed
13,8v/5Amp 78H05 based power supply for portable
I wanted a compact but powerful and versatile power supply
13.8V 20A linear power supply
Linear power supplies for communication equipment
