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 […]
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 […]
1.25V to 25V Adjustable Power Supply Circuit with IC LM350
LM350 is adjustable voltage regulator IC, which gives output from 1.25V to 25V and it can supply current up to 3A, because it can deliver more than 3A current, we must fix the LM350 on a big heat sink to remove heat properly. This 1.25V to 25V adjustable power supply circuit with the LM350 IC […]
1.2V to 30V 1A LM317 Adjustable Power Supply Circuit
Every circuit needs stable DC voltage, because power supply plays a very important role in electronics; however, AC voltage comes from main supply, so we need to convert AC to DC. Therefore, this circuit uses LM317 to make adjustable DC power supply and output voltage can change from 1.2V to 30V, with maximum output current […]
