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, ...

Many low-dropout voltage regulators include an enable-input pin that can also serve as an inexpensive alternative to a voltage-supervisor IC. Although the enable pin normally serves as a means of ...

LDOs can offer the low noise and PSRR performance to be used in wide voltage range applications such as in test and measurement systems, write Amit Patel and Steve Knoth Linear Regulators are ...

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 ...

Is it possible to design an unconditionally stable linear voltage regulator? In fact, many believe that most regulator ICs are unconditionally stable. The answer is both simple and complex, if it is ...

Low-dropout (LDO) linear regulators have been widely used in noise-sensitive applications for decades. Nevertheless, noise requirements have become tougher to meet as the latest precision sensors, ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

[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 ...

Power supply design is introduced starting with a simple half wave and full wave rectifier capacitor filter power supply. The student will develop a design process that details performance ...

Nisshinbo Micro Devices, a Tokyo-based semiconductor company, has unveiled a new quad-channel power management integrated circuit (PMIC).
