Noise Sensitive Applications Want Ultralow Noise LDO Regulators

Amit P. Patel, Senior Design Engineer, Power Products & Steve Knoth, Senior Product Marketing Engineer – Power Products, Linear Technology Corporation

Linear Regulators are integrated circuits that step a voltage down from a higher voltage to a lower voltage without the need of an inductor. The low dropout linear regulator (LDO) is a special type of linear regulator in which the dropout voltage – the differential between the input-to-output voltages needed to

Determining the State of Health of Batteries Quickly and Precisely

Dipl.-Ing. Andreas Mangler, Rutronik, Dr.-Ing. Olfa Kanoun and Dipl.-Ing. Thomas Günther, Chemnitz University of Technology

When Li-ion batteries age, their performance drops. Current methods still require complex instrumented laboratory-based tests to determine how quickly and to which degree this occurs. In contrast, a procedure developed by Chemnitz University of Technology now enables quick and precise diagnosis. It ensures the re

Figure 1. A brushed DC motor in its very simplest form, using a permanent magnet for the stator field, safety pins as the brushes and a wire coil as the armature winding. It draws its power straight from a battery.

Why Brushed DC Motors Still Have a Role to Play in Modern Designs

Robert Huntly, contributing on behalf of Mouser Electronics

A brushed DC motor will start turning when you apply a DC power source to its brushes. These make contact with the commutator (part of the moving rotor) and cause a current to flow through it. The fixed part of the motor – the stator – provides the constant magnetic field that interacts with the current fl

Figure 1. Power rail voltages and tolerances required by ICs continue to decrease. These dynamics challenge traditional oscilloscope measurement approaches as the noise of the scope and probe system impairs the ability to make accurate measurements of small signals.

Precise Power Integrity Measurements

Joel Woodward, Strategic Oscilloscope Planner at Rohde & Schwarz in Munich

Development teams face increasing power integrity challenges. FPGAs, ASICs, and standard components semiconductor devices continue to increase in gate count. Each of the millions of gates on an integrated circuit requires current to switch. As devices can consume tens of amps and total power must be managed, DC
