DC Regulator supply 15V non transformer

Friends at don’t like large-sized of a transformer. I begs for to advise 15VDC regulator power supply can give the trend current get low about 80mA not exceed. But enough will usable small-sized circuit has comfortablely. Think I uses Zener Diode be formed help maintain one’s position volt be stable , and use Transistor help enlarge current tallly increasingly. Make this circuit is usable well , But friends as a result must use the carefulness specially , because apply to the level voltage tall directly 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.

Dual linear regulator +15V -15V by Transistor Only

When friends want Dual Regulator +15V GND -15V. Usual like to to use the integrated circuit LM7815 and LM7915. But sometimes seek the integrated circuit no will do ? Today I leads old circuit , but be worthy give friends. Try out the one choice use the transistor and Zener Diode 15V can use be Dual Regulator +15V GND -15V get also. Although complicated more but economize and seek easy equipment certainly. For equipment other list friends can seek pay back can. such as Q1 2N4053 use the number BD140 can replace Q2 – 2N3446 use the number BD139 can replace. Seek buy easy and the price is inexpensive. Request friends have fun Dual linear regulator +15V -15V Circuit , please yes.
