Micrel Previews Industry Breakthrough SuperLNR(TM) Family of Low Noise Regulators Featuring Efficiency of Switching Regulators
SAN JOSE, Calif., June 13 /-- Micrel Inc., (NASDAQ:MCRL), an industry leader in analog, high bandwidth communications and Ethernet IC solutions, today previewed a new family of 'SuperLNRs' (Low Noise Regulators) that feature the advantages and ease of use of LDOs with low noise, high PSRR, ultra-fast transient performance, while providing the efficiency of a switching regulator. Micrel's new SuperLNR family combines the "good" characteristics of both linear regulators and DC-to-DC converters to produce a new generation of easy-to-use Low Noise Regulators. The MIC38300, the first device in this family, is a 3A voltage regulator housed in a tiny 4mm x 6mm MLF(R) package that produces less than 5mV of output noise and 70dB of PSRR. Industry leading, ultra-fast dynamic performance also allows the MIC38300 to maintaining less than 30mV of output voltage deviation even during fast load transients. The IC is targeted at applications that need an easy upgrade from LDOs as power dissipation becomes an issue or where low-noise performance, small size and fast transient performance are paramount. Target markets include point-of-load and digital IC power regulators for networking, servers, wireless base stations, industrial and RF applications. The IC is available in sample quantities with pricing starting at $3.95 for 1K quantities.
"As supply voltages continue to move lower, the output noise and transient response associated with a switching regulator poses a significant challenge for engineers," noted Ralf Muenster, Micrel's marketing director for power products. "The MIC38300 creates the perfect low noise power supply for voltage sensitive point-of-load applications while combining the efficiency of a switcher with ease-of-use, transient performance and the low noise of an LDO -- all resulting in an extremely small solution size that fits into the footprint of an LDO."
The MIC38300 features an input voltage range of 3.0V to 5.5V and adjustable output voltages as low as 1V. The solution requires no external inductor and fits into a total solution footprint of less than 40mm squared. The MIC38300 has a junction operating range from -40 deg C to +125 deg C.
