Micrel Rolls Out Dual 150mA, Ultra Low Noise LDOs
Micrel Inc., (Nasdaq:MCRL) launched a new family of dual ultra-low dropout voltage (ULDO™) linear regulators. The MIC5310 is the first in a series of dual LDOs simultaneously offering ultra low dropout voltage of 35mV@150mA, more than 70db power supply ripple rejection (PSRR) and ultra low output noise. The part is offered in a tiny 2 mm x 2 mm 8 pin leadless MLF® package making it ideal for today's most demanding portable applications including cellular phone RF power, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players (PMP) and PC cameras.
"Today's portable applications continue to demand increasingly smaller solution sizes without compromising on specifications or performance," noted Ralf Muenster, Micrel's Director of Marketing for Power Products. "Micrel's new MIC5310 gives engineers significant advantages over solutions currently on the market, particularly in applications where maintaining high PSRR under low input voltage-to-output voltage conditions is crucial. With its breakthrough performance and diminutive size, this series should set the standard of excellence that others will follow."
The MIC5310 integrates two independently-controlled, high performance LDOs that offer exceptional transient performance while requiring only very small and inexpensive 1µF ceramic capacitors. Both LDOs feature a low quiescent current of 75Ω per output, a fast turn-on time of 30µsec, current limit and thermal shutdown protection, and can operate from -40°C to 125°C. The IC is currently available in volume, with pricing starting at $0.60 for 1K quantity. Additional parts are expected to be launched throughout 2006.
