Microsemi Announces LX8815 Series of Dual LDOs

Microsemi Corp. (Santa Ana, CA) announced that its power management division has developed a new dual-circuit low dropout regulator (LDO) for its lineup of power management integrated circuits. Designated the LX8815 Series, the device, which combines two 1A regulator circuits in a single package, is used to regulate power on circuit boards of applications that include computer peripheral devices, battery charging circuits, and instrumentation.

Assembly process enhancements enabled Microsemi designers to package its new LDO circuits in a manner that the company believes provides superior thermal characteristics, improved operating margin, as well as saving space. The new surface mount regulator stands less than 2mm tall and has a footprint of 9.52mm x 10.67mm, which replaces two regulators, saving 70 percent board space compared to the TO-263, which requires 10.67mm x 15.87mm each.

"We work closely with customer design groups to identify ways to help them meet their ever-more-demanding space and cost targets," said James J. Peterson, president of Microsemi's power management business. Manuel Lynch, Microsemi's vice president of marketing and business development, pointed out that offering a breadth of power management solutions having unique design characteristics is fundamental to the company's new product development strategy. "Now that power management is Microsemi's largest business, we're focusing more and more on expanding this part of our product portfolio through new and enhanced process developments, coupled with Microsemi's exceptional packaging capabilities," said Lynch.

The LX8815 costs $0.94 in OEM quantities of 1,000. The series is available for immediate sampling.
