This family is offered in a miniscule 1.0 mm x 1.0 mm 6 pin leadless thin MLF package making them ideal for small portable applications possible including cellular phones, RF power, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players (PMP) and PC cameras. The MIC5380 and the MIC5381 are currently available in volume quantities, with pricing starting at $0.25 for 1K quantities.
This tiny new LDO family sets a new benchmark 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 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 -40degC to 125degC.
