Micrel Sets High Water Mark With New Low Input Voltage Dual LDO Family for High Efficiency Applications
SAN JOSE, Calif., July 31 -- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC5313/4/5/6, a new family of low input voltage capable, low dropout regulators. The MIC5313/4/5/6 family integrates two LDOs capable of operating from an input voltage as low as 1.7V, while consuming only 37 Micron-A total quiescent current. The MIC5313/4/5/6 are all currently available in volume, with pricing starting at $1.29 for 1K quantities. Samples can be ordered on line on Micrel's web site at: http://www.micrel.com/ProductList.do.
"Power efficiency remains a constant focus for designers regardless of the application. Lowering the input supply voltage used by an LDO increases system efficiency," noted Andy Khayat, Micrel's director of marketing for portable power products. "Micrel's new MIC531x family of LDO regulators enables designers to regulate from low voltage supply rails, such as 1.8V, offering excellent efficiency and the lowest cost for a low-voltage to low-voltage conversion requirement."
The MIC531x family is designed with very low dropout voltage in order to regulate from low voltage rails and provide the highest conversion efficiency possible. Each one of the dual regulator can supply up to 300mA of output current, while only consuming 37 Micron-A total quiescent current when both channels are enabled. The combination of low quiescent, low input voltage capability and low quiescent current allow the MIC531x family to be used in demanding applications that need to be powered up at all times. The MIC5313/4/5/6 product family allows use of very small ceramic output capacitors, which reduces required board space and component cost. The product family is available in fixed output voltages. In addition, this family offers high PSRR, POR, voltage scaling, fast turn-on time, current limit and thermal shutdown protection, and can operate from -40 degrees C to 125 degrees C. The MIC5313/15 is offered in a 2mm x 2mm Thin MLF(R) 10-lead, and the full featured MIC5314/16 is offered in a 2.5mm x 2.5mm Thin MLF(R) 12-lead package.
