Tiny 1.2V Regulator Controls Power-Up Sequencing in Microprocessors biz.yahoo.com SAN JOSE, Calif., May 16 /PRNewswire/ -- A tiny, low-voltage, regulator for power-up sequencing in microprocessors is now available from Micrel Semiconductor (Nasdaq: MCRL - news), an industry leader in power management and high-speed communication ICs. Capable of providing up to 150mA, the new MIC5248 is equipped with power-good output.
This power-good feature of the MIC5248 makes it ideally suited for power-up sequencing in microprocessors. It alerts the processor when the output of the regulator has reached and settled on its intended value, allowing the processor to come up gradually. The regulator is also capable of alerting the processor when a fault condition occurs and the output is out of regulation.
``Available in the IttyBitty(TM) SOT23-5 package, the MIC5248 comes with a fixed 1.2V output. Like all of Micrel's new generation of CMOS regulators, it features fast transient response, low ground current, and uCap performance,'' said Lisa Wong, LDO product marketing engineer.
Micrel's uCap regulators are stable with smaller ceramic output capacitors, eliminating the need for larger, less reliable tantalum capacitors.
When purchased in a quantity of 1,000, price for the MIC5248 starts at $0.56. Samples are available, and production quantities are stock to 8 weeks ARO.
