Milpitas, Calif. - Sipex Corp.'s SPX3819 low-dropout linear regulator is now available in 1.8-, 3- and 3.1-V fixed-output voltages. These tiny LDOs can deliver up to 500 milliamps of continuous output current with 340 mV of dropout voltage and low-noise output of 40 microvolts rms. To optimize battery life, the SPX3819 operates at a range of 2.5 V to 16 V with very low supply current of 90 microamps, which drops to nearly zero in shutdown. Packaged in a five-pin SOT-23, it starts at 75 cents each in lots of 1,000.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
