With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

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 ...

Download this article in PDF format. Analog semiconductor companies release buck-regulator chips so often you might think nothing of it. Yet there’s an enormous amount of work that goes into getting ...

[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 ...

Linear Technology introduces the LTM8020, the first in a new family of DC/DC uModule regulator systems that operate from higher voltage input supplies of up to 36V (40Vmax). The LTM8020 is a 200mA ...

National’s family of Simple Switcher step-down voltage regulators offers a wide input voltage range from 4.5V to 42V, which allows for wide-voltage transients from 12V and 24V input rails. Internal ...

A single, simple measurement is described that allows the determination of the ESR required to achieve a desired phase margin, using a particular value of output capacitor. Solving the ESR requirement ...
