Voltage regulator plays a very important role in electronics circuit, because many devices need stable DC voltage, but sometimes input voltage is only little higher than output voltage, so in this case normal regulator does not work properly. Therefore, we have used a LDO regulator, LDO means Low Dropout Regulator and it can regulate voltage […]
9V 2A to 3A Transistors Based Regulator Circuit
When our project needs real power then normal adapter is not enough, sometimes battery drains fast and cheap adapters fail; Therefore, this 9V 2A to 3A Transistors Based Regulator Circuit is best solution, with strong output, smooth DC and long life performance. However, battery is not good for high current load, so we used transformer […]
Zener Controlled 9V Regulator Circuit with TIP41 Transistor
Every electronic project requires clean and stable power because a circuit cannot operate properly without a reliable voltage supply. An unstable power supply can cause the circuit to restart unexpectedly or even damage its components. Since AC mains voltage is high and unstable, we cannot use it directly, instead, we must first convert it to […]
CD4066 Analog Switch with 555 Timer Circuit
In my previous article for Switch Selectable Four Frequency Pulse Generator Circuit i selected the frequency using manual switches; however, this circuit replaces manual switching with electronic switching by using the CD4066B quad bilateral switch, which the 555 timer controls automatically. The CD4066 is a quad bilateral switch IC that contains four independent analog switches […]
Switch Selectable Four Frequency Pulse Generator Circuit
This Switch Selectable Four Frequency Pulse Generator Circuit is a simple astable oscillator that uses the popular 555 timer IC in astable mode and also users can change the output frequency in four steps by pressing the switch to select different capacitors. Here, output is the square wave signal and it works in astable mode, […]
3A PWM Power Generator Circuit with IC 555 and LM350
This circuit is for a high power pulse generator which uses 555 timer IC as a pulse oscillator and IC LM350 regulator which gives high current output; also IC 555 can handle high current up to 3A and gives small output current and IC LM350 provides output current upto 3A. Therefore, this 3A PWM Power […]
