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.

Muti lab power supply 15V,30V,45V,60V

Friends ever meet a problem experience Electronics Circuit at want the level Voltage various? I like to make any circuits form old electronic parts,Because it is very cheap, and a great challenge. Today I begs for to suggest Muti lab power supply 15V,30V,45V,60V Circuit may meet the requirement of friends get. By it is the circuit is simple use the transistor = 4 pcs (C1061,A761,Driver 2N3053,2N4037) only and We use a Zener diode 30V (2pcs) has a constant voltage level. The transistor have equiv number many the number. but however this circuit inappropriate for you who want current tall. Because it gives current 0.5A only just. This circuit idea friends, may apply the work has please yes.

Dual DC Regulator 15V using C1061 and A761

A friend of me you one take an interest a side Sound Audio the very. He takes an interest to want to build Pre tone Control which use the integrated circuit OP-AMP. By these circuit often use power supply Model Dual DC Regulator which have Voltage Value about +15V Ground and -15V. I then advise to give him chooses to use the integrated circuit number LM7815 and LM7915 because good convenient. But in sometimes using integrated circuit inappropriate suit follow the situation that. Such as seek buy the integrated circuit no, the expensive etc. I then advise Dual DC Regulator 15V using Transistor C1061 and A761. Because use Transistor all , seek easy and sometimes you still antiques sheep comes to use can replace. By Transistor use get many the number , TIP41,TIP31,MJE3055 , and , TIP42,TIP32,MJE2955 etc. Unless still systematically protect through the circuit with. And still give current about 1A-2A as well. Almost forget friends must use transformer 1-2A size with. And me press model PCB for the convenience of friends with. Request have fun Dual DC Regulator 15V using C1061 and A761 , please sir.
