Micrel Inc. has launched the MIC68220, a compact dual 2A LDO regulator aimed at powering FPGA and microcontroller (MCU) applications including broadband modems, routers, STBs, home entertainment systems, storage networks, wireless base stations and car infotainment systems.

Micrel's MIC68220 offers an extremely low component count solution with superior flexibility for supporting a wide variety of voltage supply requirements for current and future FPGAs, microprocessors and other logic ICs. The IC's low minimum single input voltage of 1.65V and 400mV dropout minimises power dissipation ?all in a single compact device with the smallest possible PCB footprint.

The chip also features ramp control, which enables the solution 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 between 0.8V to 5V in one compact 4-by-5mm MLF- 20 package to support core and I/O voltage supplies, accurate to within two per cent over temperature.

The MIC68220 is currently available in volume and pricing starts at Rs.149.56 ($3.30) for 1,000 quantities.
