Micrel Sets High Water Mark With New Low Input Voltage Dual LDO Family for
High Efficiency Applications

SAN JOSE, Calif., July 31 /PRNewswire-FirstCall/ -- Micrel Inc.,
(Nasdaq: MCRL), an industry leader in analog, high bandwidth communications
and Ethernet IC solutions, today launched the MIC5313/4/5/6, a new family of
low input voltage capable, low dropout regulators. The MIC5313/4/5/6 family
integrates two LDOs capable of operating from an input voltage as low as 1.7V,
while consuming only 37 Micron-A total quiescent current. The MIC5313/4/5/6
are all currently available in volume, with pricing starting at $1.29 for 1K
quantities. Samples can be ordered on line on Micrel's web site at:

"Power efficiency remains a constant focus for designers regardless of the
application. Lowering the input supply voltage used by an LDO increases system
efficiency," noted Andy Khayat, Micrel's director of marketing for portable
power products. "Micrel's new MIC531x family of LDO regulators enables
designers to regulate from low voltage supply rails, such as 1.8V, offering
excellent efficiency and the lowest cost for a low-voltage to low-voltage
conversion requirement."
The MIC531x family is designed with very low dropout voltage in order to
regulate from low voltage rails and provide the highest conversion efficiency
possible. Each one of the dual regulator can supply up to 300mA of output
current, while only consuming 37 Micron-A total quiescent current when both
channels are enabled. The combination of low quiescent, low input voltage
capability and low quiescent current allow the MIC531x family to be used in
demanding applications that need to be powered up at all times. The
MIC5313/4/5/6 product family allows use of very small ceramic output
capacitors, which reduces required board space and component cost. The
product family is available in fixed output voltages. In addition, this
family offers high PSRR, POR, voltage scaling, fast turn-on time, current
limit and thermal shutdown protection, and can operate from -40 degrees C to
125 degrees C. The MIC5313/15 is offered in a 2mm x 2mm Thin MLF(R) 10-lead,
and the full featured MIC5314/16 is offered in a 2.5mm x 2.5mm Thin MLF(R)
12-lead package.
