ELECTRONICS: Linear Technology Corp.’s LT3060 is a high voltage, low noise, low dropout voltage linear regulator. The IC delivers up to 100 mA continuous output current with a 300 mV dropout voltage at full load. The LT3060 features a wide input voltage range of 1.6 to 45V, delivering adjustable output voltages from 0.6 to 44.5V. A single capacitor provides both programmable ultra-low noise operation - only 30 µVRMS across a wide bandwidth of 10 Hz to 100 kHz - and reference soft start functionality, preventing output voltage overshoot at turn-on. The LT3060’s output voltage tolerance is highly accurate at ±2 percent over line, load and temperature. The IC’s wide input and output voltage ranges, fast transient response, low quiescent current of 40 µA (operating) and <1 µA (in shutdown) make it an excellent choice for portable battery-powered systems that require optimum run time, and usage in automotive, industrial and avionic power supply applications.
The LT3060 operates with a very small, low cost, ceramic output capacitor, optimizing stability and transient response. It is stable with only a 2.2µF output capacitor. These tiny external capacitors can be used without the necessary addition of series resistance (ESR) as is common with many other regulators. The LT3060’s internal protection circuitry includes reverse-battery protection, reverse-output protection, reverse-current protection, current limit with foldback and thermal limiting.
The LT3060EDC, LT3060IDC, LT3060ETS8 and LT3060ITS8 are housed in 8-lead 2 x 2mm DFN and 8-lead ThinSOTTM packages, respectively, offering a compact footprint. The “E” and “I” grade versions are available from stock with an operating junction temperature of -40 to 125C and are priced at $1.21 and $1.33 each, respectively. The LT3060HTS8 “H” grade and LT3060MPTS8 “MP” grade are available from stock and offered in the ThinSOT package, with respective operating junction temperatures of -40 to 150C and -55 to 125C, and are priced at $1.67 and $4.34 each, respectively.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
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.
