120V Linear Regulators From Micrel Offer Industry-Leading Quiescent Current and Low-Noise Performance

SAN JOSE, CA, Aug 01 (MARKET WIRE) --
Micrel Inc., (NASDAQ: MCRL), an industry leader in analog, high bandwidth
communications and Ethernet IC solutions, today rolled out the MIC5281
and MIC5282, two high performance linear regulators designed for
noise-sensitive applications such as industrial, networking, telecom
infrastructure equipment and bias power supplies. Both the MIC5281 and
MIC5282 are currently available in volume quantities, with 1K pricing
starting at $1.00 and $1.10 respectively. Samples can now be ordered at:

"With its industry-leading quiescent current of 6uA and PSRR of greater
than 90dB, both the MIC5281 and MIC5282 offer a plethora of benefits to
the designers that are focused on improving efficiency and low noise in
industrial and telecom systems," noted Doyle Slack, senior marketing
director for Analog. "Along with these core features, the linear
regulators offer the benefits of withstanding transient input voltages of
up to 120V and generating a clean voltage rail to maximize system
performance."

These devices operate over a very wide input operating voltage range, up
to 120V DC, and supply an output current of up to 25mA and 50mA
respectively. Ideal for high input voltage applications such as
industrial and telecom, the MIC5281 and MIC5282 offer +/-3 percent
initial accuracy, extremely high power supply rejection ratio ( > 90dB)
and ultra-low quiescent current of 6uA. The devices are offered in both
fixed output voltage (3.3V/5.0V) and adjustable output voltage (1.27V to
5.5V) options. The solutions operate over the -40degC to +125degC
temperature range and are available in lead-free, RoHS compliant 8-Pin
ePad MSOP and 8-Pin MSOP package options. Data sheet and support
documentation can be found on the Micrel website: www.micrel.com.
