This adjustable power supply is capable of delivering a maximum output of 12 A with an adjustable voltage from 4 V to 20 V through many LM317 ICs connected in parallel. It will allow testing of any device requiring a significant power supply, such as a direct current motor, a car amplifier, or even a […]

How to Modify 78XX, LM323, LM350, LM317 Voltage Regulator Circuits
In this article I have explained many different methods of modifying voltage regulators ICs to improve their voltage and current handling characteristics. We learn how to externally modify these regulators using transistors and ICs for upgrading their current and power handling capacities. We discuss how to modify 78XX ICs, LM317 ICs, LM350 ICs, and LM323 […]
LM317, LM338, LM396 Calculator
This LM317, LM338 calculator software is used as a tool to determine the value of the voltage adjusting resistor needed to assign the output of an LM317 to an allocated degree. Normally R1 is 220 ohms or 240 ohms, however it could very well be a different value for instance 150 or 470 ohms. Go […]
Single LM317 based MPPT Simulator Circuit
To make this simple MPPT circuit we first modify a standard LM317 power supply circuit into a buck converter then configure it with a solar panel for implementing an MPPT function. Modifying a LM317 Power Supply into an MPPT Solar Optimizer In our previous article I have explained how a standard LM317 power supply could […]
LM317 Variable Switch Mode Power Supply (SMPS)
So far in this website we have studied LM317 based linear power supply circuits, here I have explained how an LM317 can be executed as a variable switch mode power or SMPS with zero loss. LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage […]
0-60V LM317HV Variable Power Supply Circuit
The high voltage LM317HV series of ICs will allow to go beyond the traditional voltage limits of an LM317 IC and enable controlling supplies that may be as high as 60V. 0-60V Regulation with a Single IC LM317 Therefore now you can build a universal 0-60V regulated power supply circuit loaded with all the essential […]
