LDO Powers Processor Cores Down To 0.9V

Targeting low-voltage processor cores, the MIC49150 1.5A dual supply, low dropout regulator (LDO) can output voltages as low as 0.9V. Operating on an input voltage down to 1.4V, the main power source to the device requires just 500 mV of headroom. The LDO is offered in two package types: MSOP-8 with peak output of 1.5A, and S-Pak with 1.5A continuous output capability. Other features include thermal shutdown, current limit protection, and a temperature range from -40°C to +125°C. Employing the company’s µCap technology, the regulator requires just a single 1 µF ceramic output capacitor. As a result, the device is said to be highly tolerant of any capacitance used on its output. Price for either package type is $2 each/1,000. MICREL INC., San Jose, CA. (408) 944-0800.
