Micrel Semiconductor Introduces New MIC5248 Low-Voltage Regulator

A small, low-voltage regulator for power-up sequencing in microprocessors is now available from Micrel Semiconductor (San Jose, CA). Capable of providing up to 150mA, the new MIC5248 is equipped with power-good output.

According to the company, 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 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, according to the company.

The price for the MIC5248 starts at $0.56 when purchased in 1,000-piece quantities. Samples are available and production quantities are stock to eight weeks ARO.
