Circuit Project Electronic

A common need in many systems is to obtain positive and negative supplies from a single battery. Where current requirements are small, the circuit shown is a simple solution. It provides symmetrical +&- output voltages, both equal to one half the input voltage. The output voltages are referenced to pin 3, output common. If the [...]

Friends ever meet a problem experience Electronics Circuit at want the level Voltage various? 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,A761,2N3053,2N4037) only and Zener Diode ZD30V [...]
