[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

This article presents linear regulators and the computation of its efficiency. It also describes the advantages and other properties of a linear regulator, as well as the low drop out (LDO) regulator, ...

Solar-photovoltaic arrays seem to get cheaper and more efficient every day, making them increasingly practical in renewable and/or remote power supply applications. Still, the voltage generated by any ...

The power supply for new products is often taken for granted. However, judging from recent experience, it’s clear that the power supply for new industrial equipment or Internet of Things (IoT) ...
