Micrel Inc. has introduced the 4A MIC68400, the latest member of its MIC68000 LDO family designed for powering FPGA, CPLDs, DSPs and MCUs. The devices in this family are aimed at applications such as broadband modems, routers, servers, storage networks and wireless base stations.

"With the introduction of the MIC68400, Micrel has the broadest portfolio of solutions featuring integrated sequencing, tracking and ramp control," noted Ralf Muenster, Micrel's director of marketing for power products. "The MIC68400 technology is reflective of the entire MIC68000 family; it offers a very flexible framework in order to meet the complex power-up protocols many of today's advanced mission critical systems require for reliable operation."

The MIC68400 supports various power-up and power-down protocols such as sequencing, tracking and ratiometric tracking that can be implemented very easily with the use of few passive components. Additionally, multiple MIC68400 and/or other devices within the MIC68000 family can be daisy-chained together for a complete synchronized system power-up and power-down. The IC operates from a wide input range of 1.65-5.5V and supports an output voltage as low as 0.5V with 2 percent accuracy. Integrated protection features include thermal, current limit and reverse current protection. The MIC68400 is offered in a tiny 16-lead 4-by-4mm MLF package.
