[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 ...

In Figure 1, the 5V linear regulator (U1) delivers as much as 150mA of load current when operating by itself. Operating with the external pass transistor shown (Q1), the circuit maintains 5V ...

A power converter generates a voltage and current for a load with all the output power coming from the input source – no energy is manufactured inside the converter and some inevitably gets used by ...

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) ...

Linear Technology’s 1.5-A LT3081 low-dropout (LDO) linear regulator targets industrial applications (Fig. 1). Today’s designers already have a plethora of switching regulator options, but Linear CTO ...
