Simple 24V 1A DC Power Supply Circuit using 7824 IC

Last updated on 24 March 2026 by Admin-Lavi Leave a Comment

In this tutorial, we will talk about Simple 24V 1A DC Power Supply Circuit using 7824 IC, which convert AC voltage into stable DC output and gives around 1A current. Also, many electronic circuits need fixed 24V supply, so this circuit is very useful, as it give clean and steady voltage with low ripple. This […]

DC Voltage Splitter Circuit with Op-Amp and Transistor Buffer

Last updated on 24 March 2026 by Admin-Lavi Leave a Comment

In my previous post I already made a Simple Voltage Splitter Circuit using uA741 Op-Amp, but this time I added transistors so circuit can handle more current and work more strong. This DC voltage splitter circuit with op-amp and transistor buffer change single DC supply into dual supply like +V and –V with one virtual […]

High Current 5V 3A Voltage Regulator Circuit

Last updated on 22 March 2026 by Admin-Lavi Leave a Comment

This High Current 5V 3A Voltage Regulator Circuit gives regulated 5V output with high current capacity. Normal 7805 IC gives around 1A current, but in many projects, this current is not enough, so we add a power transistor to increase current up to around 3A. This circuit also uses bridge rectifier and filter capacitors to […]

How to Increase 7805 Output Voltage using Diodes

Last updated on 21 March 2026 by Admin-Lavi Leave a Comment

In this post we will understand How to Increase 7805 Output Voltage using Diodes. Normally, L7805 gives fixed 5V output, but by adding diode in ground line, we can increase output voltage little bit. This method is simple and is with low cost, as it is useful when we need slightly higher voltage like 5.7V […]

Simple Backup Power Supply Circuit using JFET Transistor

Last updated on 21 March 2026 by Admin-Lavi Leave a Comment

In this article, the circuit gives temporary backup power to low current electronic systems as it uses JFET transistor like 2N3819. This Simple Backup Power Supply Circuit using JFET Transistor which charges a capacitor at 15V input and gives approximate 4V-6V output during power failure, because it depends on transistor characteristics, resistor tolerance and load […]
