AMS1117 1A LDO Voltage Adjustable Regulator Circuits
It is a low-drop regulator, which means that it reaches its maximum efficiency with an input voltage that only needs to be a little bit higher than the output voltage, or around 0.9V to 1.2V. Read more
Adjustable 7805 and 7905 Voltage Regulator Circuit
Let’s build an adjustable dual power supply circuit using a 7805 and a 7905 IC. The output can be adjusted from +5V to +25V and -5V to -25V at 1A. It is also a great way to understand the basics of OP-AMP circuits. Read more
0-12V 3A Variable Power Supply Circuits
In a normal circuit, the general LM350 regulator has a start voltage of 1.25V. But this circuit is special that start of 0-volts. We use only one IC and a few other components. So cheap and easy for you. Read more
5V 3A Power Supply circuits using LM350 | transistors
See 5V 3A power supply circuit using LM323K or LM350 or 7805 by helping of the power transistor. For digital load, microcontroller, even raspberry-pi. Read more
