Variable Voltage Regulator 0V-30V DC/2A Using LM723

A D V E R T I S E M E N T

This is a circuit diagram of a simple circuit regulated power supply, these circuits in the control by IC LM723. In principle, based on the known LM 723, which encourages the transistor Q1 [2N3055]. Voltage settings, the cost to the potentiometer R1 from 0V-30V DC rude. In order for us to reach 30 V, will have to supply the transformer TR1, it provides all the required load current, a different output voltage will be found at the level of 26 V rough. Important is the use of a good heatsink for the transistor Q1, as well as good quality potentiometer in place of R1. The following is a schematic drawing:

Component :

R1=1.2Kohm
R2=680ohm
R3=0.33ohm/5W
R4=15Kohm
R5=3.9Kohm
P1=4K7 LOG. POT.
C1=4700uF/63V
C2=100nF63V MKT
C3=4.7nF63V MKT
C4=220uF/63V
Q1=2N3055
IC1=LM723
B1=Brindge 100V 5A
TR1=220VAC/ 27V 4A
F2=2A Slow Fuse
