SAN JOSE, California, April 7 /PRNewswire/ --

Micrel Inc., (Nasdaq: MCRL), an industry leader in analog, high bandwidth
communications and Ethernet IC solutions, today launched the MIC5331/32/33 a
new dual channel micro-power LDO regulator family ideally suited for today's
power-hungry, battery-powered electronics including mobile phones, PDAs, MP3
players, personal navigation devices (PND), digital still cameras and
handheld instruments. This MIC533x family integrates two low quiescent
current 300mA LDO regulators and up to two Power On Resets (POR) circuits
into a 2mm x 2mm Thin MLF(R) package, allowing hand-held customers to power
up and still save precious battery time. The MIC5331/2/3 family is currently
available in volume quantities with pricing starting at US$0.66 for 1K
quantities.

"Today's portable applications continue to increase functionality while
demanding equal or improved operating times from a single battery charge,"
noted Andy Khayat, Micrel's director of marketing for portable power
products. "Micrel's new MIC533x family of LDO regulators gives customers the
ability to power up the most advanced features and the integration to reduce
the solution size while using the absolute minimum amount of power. This
gives designers the space savings and flexibility they need to create the
latest and most feature-rich hand-held products possible."

The MIC533x family provides two 300mA LDO regulators with very fast
transient response to any load change condition and up to two POR circuits
with adjustable delay time. The MIC533x family achieves this in spite of only
consuming 40uA total while both outputs are enabled. This combination of
integration, high performance and low power consumption makes the MIC533x
family suitable for all applications in portable electronics. The
MIC5331/32/33 is a micron Cap 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
high PSRR and full protection circuitry including current limit and thermal
shutdown protection, with an operating junction temperature range of -40
degrees C to 125 degrees C.
