Micrel Announces New Ultra Low Power, High Performance LDOs
MIC5311/12 Feature LowQ(TM) to Reduce Operating Current by Up to 75 Percent
SAN JOSE, Calif., Feb. 14 - Micrel Inc., (NASDAQ:MCRL), an industry leader in Power, Connect and Protect IC solutions, today launched two new ultra low standby power, high performance Low Dropout Regulators (LDOs). The chips are aimed at the latest consumer applications requiring extended battery time and enhanced performance including cellular and PCS phones, wireless modems, PDAs and MP3 players. The chips are currently sampling with volume quantities available within 10 to 12 weeks. Pricing starts at $0.81 in 1K quantity.
"As handheld products continue to take on more features and functions, battery life becomes more significant," noted Tony O'Brien, Micrel's director of marketing, power products. "The MIC5311 and MIC5312 address the growing need in many consumer products for ultra-low battery power by offering up to a 75 percent reduction in standby operating current."
Fabricated using Micrel's proprietary CMOS technology, the MIC5311 and MIC5312 are dual output, low operating current, low dropout regulators that feature a second, even lower LowQ(TM) (Low Quiescent) operating current mode. MIC5312 adds an integrated on-board power-on reset supervisor with programmable delay.
Both ICs offer an input voltage operating range of 2.5V to 5.5V while supplying up to 300mA of current from each output. LowQ(TM) Mode offers 7micronA total quiescent current operation while still supplying up to 10mA output current. Logic level signals, applied to the Enable pins, independently control each output. And with both outputs disabled, the chips' operating current drops to 0.1micronA. Both ICs are offered in tiny 3mm x 3mm MLF(TM)-10 leadless packaging, thus saving valuable board real estate.
"Micrel's design prowess revolves around our ability to innovate with technology offerings that are ahead of feature and function trends," noted Bob Whelton, executive vice president of Operations, Micrel. "The MIC5311 and MIC5312 are reflective of Micrel's design philosophy, offering aggressive performance improvements that enable designers to meet consumer trends with cost-effective and space-conscious packaged solutions."
