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 […]

Connecting Voltage Regulators 78XX in Parallel for High Current
In this post we investigate how to connect popular voltage regulator ICs such as 7812, 7805 in parallel for acquiring high current output from the ICs. Voltage regulator chips mostly have their maximum current output specs fixed to some predetermined levels. Increasing them to a higher level would normally call for external out board transistors […]
