Let’s build an adjustable dual power supply circuit using a 7805 and a 7905 IC. The output can be adjusted from +5V to +25V and -5V to -25V at 1A. It is also a great way to understand the basics of OP-AMP circuits. Read more
Small appliances have microcomputer that requires 5V power supply. Why it can use only 1.5V battery? The 1.5V to 5V boost converter circuit inside them. Read more
Your amplifier may sound better than before. Just change the appropriate power supply circuit. Multiple levels of output voltage. For example 15V Dual regulator for pre amplifier. And 38V Dual for main amplifier etc. Read more
This is dual 15v power supply schematic, using LM7815,LM7915,and power transistor and zener diode for voltage stable voltage 15 volts positive and negative. […] Read more
This is a 0-60V, Dual Variable power supply circuit using LM317 and LM337 at 1.5A current so can builds to easy with PCB layout, adjustable voltage VR1,VR2 […] Read more
