Dual Variable Regulator power supply 5-25V by LM7805,LM7905

When you want Dual power supply Variable Regulator be simple. I begs for to advise this circuit, because use the integrated circuit LM7805 and IC 7905. Make have Voltage +5V to +25V and -5V to -25V unless. VR1 for Adjustable + Volt output,VR2 for adjustable -volt output. Still pay current get about 1A enough with general usability. The important factor is you should use Transformer at enough size doesn’t lower 2A and IC all stick let off the heat with. The detail is other see in circuit picture better sir.

High Current Variable Voltage Regulator 2-36V 10A

Yesterday I no enhance the circuit in my blog. Today lead High Current power supply 10A and Can Adjustable Voltage or Variable Voltage Regulator 2V to 36V. By the prominent point of this circuit. Be there is the a little equipment and is simple have VR1 for control Volt output. For the equipment must use the size is appropriate. If use the a little value goes to get Current not tall on schedule keep, such as The Transformer use 10A, Transistor sizes should are the number that notes , and A capacitors should choose many values especially C1 – 18000 uF , use 10000uF values wasp parallel can. For other detail , friends sees in the circuit please yes.
