Micrel Addresses Voracious Power Demands With Latest Family of Micro-Power Single LDOs

Battery-Powered Applications Get Extended Run Time in Ever-Shrinking Package Options

SAN JOSE, CA--(Marketwire - October 21, 2008) - Micrel Inc., (NASDAQ: MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today launched the MIC5326/27/37 family of devices. The new family of single output, low quiescent current LDO regulators is ideally suited for today's power-hungry battery-powered electronics including mobile phones, PDAs, MP3s, PNDs, DSCs and handheld medical instruments. This MIC5326/27/37 family of LDOs is capable of sourcing up to 300 milli Amp, while consuming only 24 micro Amp of quiescent current and still maintaining low dropout performance in a tiny 1.2mm x 1.6mm Thin MLF® package. The combination of these performance benefits provide extended battery run time for small handheld applications. The MIC5326/27/37 family is currently available in volume and pricing starting at $0.32 for 1K quantities. Samples can now be ordered on line on Micrel's web site at: http://www.micrel.com/ProductList.do.

"Today's portable applications continue to converge features, while demanding improved operating times from a single battery charge," noted Andy Khayat, Micrel's director of marketing for portable power products. "Micrel's new MIC5326/27/37 family of low quiescent current LDO regulators gives customers the perfect solution where small footprint and maximum battery life are key factors."

The MIC5326/27/37 family provides very fast transient response to any load change condition, while still maintaining high PSRR. The devices achieve this in spite of consuming just 24 micro Amps of quiescent current in a small, thermally-enhanced Thin MLF® package. This combination of high performance and low power consumption makes the MIC5326/27/37 family suitable for all portable handheld applications. The MIC5326/27/37 is a µCap design, operating with very small ceramic output capacitors, which reduces required board space and component cost; and it is available in fixed output voltages. In addition, this family offers full protection circuitry, including current limit and thermal shutdown protection, with an operating junction temperature range of -40°C to 125°C.
