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 e...

This be power supply variable regulator circuit, since 5V to 13V that current about 1A. By use IC LM7805 (3-Terminal 1A Positive Voltage Regulator) perform maintain ones position voltage, be stable that 5V. And have op-amp IC number CA3140 , help fine decorate voltage go out can modify 5V to 13V f...

Sometimes we want to use. high current at a voltage 5 volts.We can do this by using the voltage regulator IC1 positive constant number 7805.The Q1 and Q2 of circuit will serve to increase current for IC regulator.The R2 acts as the anti-saturation of Q1 and Q2. Without R2 will allow the two transist...

Voltage regulator IC’s, with 3 pins, from LM7805 and LM7812 series are excellent for usage in voltage regulator circuits. If you need higher currents, up to 3 A, you must add a complementary transistor, T2 in this schematic. In a normal design, in case of a shortcircuit, the power dissipat...
