We can use transistorized low dropout voltage regulator circuits to achieve stable output voltages. These voltages can start at 3 V and go up to 5 V, 8 V, 9 […]

The purpose of the suggested slow-start power supply circuit is to prevent the loudspeaker which is hooked up to the amplifier from producing an unpleasant and loud “thump” sound when […]

I was forced to address the issue once and for all after receiving a growing number of reader complaints about burning LEDs related to my previously released transformerless 1 watt […]

The circuit we are talking about in this article is probably one of the simplest and most cost-effective options out there. This is mainly because it uses a very small […]

You are going to be totally blown away by all the cool features that this fantastic voltage regulator integrated circuit or IC has to offer. As the name suggests this […]

Here we are discussing a pretty affordable yet surprisingly effective way to protect our power supply circuits from short circuits. This is super useful for anyone who loves tinkering with […]
