Micrel Inc. has launched a compact dual 2A LDO regulator aimed at powering FPGA and MCU applications, including broadband modems, routers, STBs, home entertainment systems, storage networks, wireless base stations and car infotainment systems.

The MIC68220 offers a low component count solution with flexibility for supporting a wide variety of voltage supply requirements for current and future FPGAs, microprocessors and other logic ICs. The chip's low minimum single input voltage of 1.65V and 400mV dropout minimizes power dissipationall in a single compact device with the smallest possible PCB footprint, the company said.

The chip also features ramp control, which enables it to support a wide variety of power-up/power-down protocols such as sequencing, tracking, adjustable turn-on/off delay and adjustable output voltage slew rate with a minimum number of external components. The MIC68220 offers independently adjustable outputs from 0.8V to 5V in a compact 4-by-5mm MLF-20 package to support core and I/O voltage supplies, accurate to within two percent over temperature.

The MIC68220 is currently available in volume and pricing starts at $3.30 for 1,000 quantities.
