The compact 5 pin L165 IC general a stabilized symmetrical power supply from a single asymmetrical power supply. The output voltage is however, half of the input voltage. One needs to add the ripple filter capacitors C1, C2, C3 and C4 and some resistors for setting the symmetry. In constructing the circuit, place the capacitors [...]
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 = 2 pcs. [...]
Friends at like to experience is digital circuit has evered to get into trouble have no 5V lab power supply ? In time wants emergency. but seek buy the integrated circuit can not. We come to try use the transistor be 5v voltage regulator circuit better. A friend who have old equipment may sure lollipop. [...]
