[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 ...

Last month we showed you how to use resistors to reduce voltage. While it's a viable solution for many cases it isn't for others. As noted before, resistors work for devices whose load remains ...

a simple regulator circuit just using two parallel transistor and potentiometer to make adjustable voltage output. a simple regulator circuit just using two parallel transistor and potentiometer to ...

“Chapter 5; Horowitz and Hill”. University students of all subjects will each have their standard texts of which everyone will own a copy. It will be so familiar to them as to be referred to by its ...

PLANO, USA: Diodes Inc. has introduced new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors designed for 48V circuits in networking, telecom and ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

This voltage regulator delivers smooth control of a constant voltage from 0 to 8 V. It protects the load against short circuits and indicates connection, overload, and output level. The series chain ...

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) ...
