Micrel Claims World’s Smallest Dual LDO Family
Micrel has launched a new family of dual low dropout voltage linear regulators. The MIC5380 and the MIC5381 are part of a new family of dual LDOs offering low dropout voltage of 155mV@150mAmp, more than 60db Power Supply Ripple Rejection (PSRR) and low quiescent current 32microA, in the smallest possible form factor.
This“This tiny new LDO family sets a new bench mark on smallest possible package form factor without compromising on specifications or electrical performance,” noted Andy Khayat, Micrel’s director of marketing for portable power products. “The MIC5380 and the MIC5381 both address the need for continuing portable size reduction while offering significant advantages over solutions currently on the market. This new addition of high performance dual LDOs offer excellent overall performance and ultra-small foot print for all space-constrained portable electronics.”
The MIC5380 and the MIC5381 integrate two high performance LDOs that offer exceptional transient response while requiring only small and inexpensive 1microF ceramic capacitors. In addition, the MIC5381 offers an auto discharge function. Both the MIC5380 and MIC5381 offer full protection circuitry including current limit and thermal shutdown protection, and an operating junction temperature range of -40°C to 125°C.
