ELECTRONICS: Linear Technology Corp. announces the LT3022, a 1A very low dropout linear regulator (VLDOTM), featuring input voltage capability down to 0.9V and adjustable output voltage down to 0.2V. The LT3022’s low VIN capability, coupled with the device’s low dropout (145mV typical at full load), make it ideal for low-voltage, high current rails in digital ICs such as FPGAs, ASICs, DSPs, microprocessors and microcontrollers. It also has applications in general high-efficiency, low-Vin-to-low-Vout conversion (for example, 1.8 to 1.5V, 1.5 to 1.2V or 1.2 to 0.9V). In addition, the device offers low power operation at only 400µA quiescent current with less than 10µA in shutdown, saving run time in handheld applications.
The LT3022 regulator optimizes stability and transient response with low ESR, ceramic output capacitors as small as 10µF. The LT3022 is highly accurate, featuring ±3 percent output voltage accuracy over line, load and temperature, 0.1% typical line regulation and 0.1% typical load regulation. The device’s bulletproof internal protection circuitry includes reverse-battery protection, reverse output protection, reverse output-to-input (current) protection, current limiting, and thermal limiting with hysteresis.
The LT3022EDHC and LT3022IDHC (16-lead 3mm x 5mm DFN) and the LT3022EMSE & LT3022IMSE (thermally enhanced MSOP-16) operate from -40 to +125C junction temperature and are available from stock in both E and I grades, providing improved thermal performance and compact solution footprints. 1,000-piece pricing starts at $2.73 each and $3.13 each for the DFN package and $2.87 each and $3.29 each for the MSOP package.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
